Getting Stronger – By Trish


Project Description

Getting stronger is a project inspired by my healing journey post ankle surgery, one of the most important processes on the road to recovery is physiotherapy. Physiotherapy recommendations is usually 2-3 times a week depending on the type of surgery. Through out my journey I have been interested in tracking my own progress hence this project explores wearable technology as a way to keep track of different physiotherapy exercises.

Getting stronger takes a look at two specific exercises I have been doing for the past year now one is ankle AROM – Inversion and Eversion. Inversion entails moving the ankle so that the foot faces towards the body while eversion involves moving the ankle so that the foot faces away from the body. This exercise is done to improve range of motion of the ankle from left to right position. The second exercise is toe towel curls which is performed using a towel or other material to scrunch. This exercise works well standing up or sitting down. This exercise is a good foot strengthening workout.

Getting stronger uses the accelerometer on the circuit playground express to keep track of the ankle AROM – Inversion and Eversion stretch to monitor the progress of range of motion on the ankle. For the toe towel curls a pressure sensor is attached to the circuit playground express to keep track of the foot strength progression.

Project Context

Getting stronger is inspired by another project I did for the Body Centric Technologies Studio Class in winter 2021 called Vibrating Knee Brace. The project documented my physiotherapy journey for my runner’s knee at the time which would cause pain and discomfort when I would run. For the project I designed a wearable knee brace that had four vibrating motors two at the top and two at the bottom connected to a CPX. The brace had four modes that were activated using the one of the on-board buttons on the CPX. When the button is pressed it would shift through the modes as follows:

  1. The CPX Neo Pixels lights up red to indicate the motors are off
  2. The CPX Neo Pixels lights up yellow to indicate the top motors are on
  3. The CPX Neo Pixels lights up orange to indicate the bottom motors are on
  4. The CPX Neo Pixels lights up green to indicate all the motors are on

The wearable was designed to be worn while someone is either running, jogging, or walking to relieve pain felt on the knee while doing these activities. The project borrowed its idea from the TENS machine which is used for physiotherapy. Getting stronger relates to this project as it also borrows ideas from existing physiotherapy exercises to keep track of progress throughout the healing process.

Sensoria® Smart Socks are a smart textile wearable designed to improve running form by keeping track of speed, pace, cadence, and foot landing. It helps a user learn how to run to avoid injury prone running styles. Sensoria smart socks are infused with comfortable, textile pressure sensors (Sensoria Fitness). They offer real-time feedback when someone striking with the heel or the ball of your foot. They help monitor foot-landing technique and the data is visualized on the Sensoria Fitness mobile app (Sensoria Fitness). The idea of getting stronger links to Sensoria as it incorporates pressure sensing with an output of the Neo Pixels on the CPX to indicate the pressure exerted during the toe towel curls exercise.

Orpyx SI® Sensory Insoles is a wearable designed to help prevent foot complications (‘Orpyx Medical Technologies Inc.’). The wearable devices offer pressure monitoring for preventing foot complications and provides physiological data that can guide patient care. It also helps to gain an understanding of a user’s activity for remote patient monitoring services and the Orpyx SI® Flex Sensory Insole System is designed to help reduce the risk of plantar foot complications. As my project looks at monitoring patient progress throughout the physiotherapy process the Orpyx Insole offers inspiration as it also uses pressure sensing for patient monitoring.

Shoulder Bird

Project Description
“Shoulder bird” is a wearable accessory I made for artistic purposes. It is supposed to imitate a bird on your shoulder, much like the pirate trope. The main purpose of the wearable is for cosplay and for fun. The project features two interactable components: A pressure sensor on the beak of the plush bird and an accelerometer on the circuit playground. The project was made with car proximity sensor in mind and how the beeps have a shorter interval and higher tone when they are too close to another object. The pressure sensor alters the tone of the speaker while the accelerometer’s Y-axis readings alters the interval between each beep. The X-axis readings alter the delay between each loop. I made the project with car sensors in mind, specifically when it beeps when reversing and how the beeps display urgency and danger through the tone and interval. I also chose the icon of a bird because I feel that the beeping of the speakers are reminiscent of a bird’s song/ tweet.
(The bird goes on your shoulder, it id fastened there by a safety pin)

Project Context
This pattern of an axolotl plush is my largest inspiration for the project as I wanted to use a similar pattern to make a plush. I incorporated the plush before anything else into the project.
Though this project isn’t a wearable project it inspired me to got for a more whimsical/ fantastical direction. THis helped me decide to make something just for the sake of art and fun.

Process: Plush
I took reference from the pattern but adapted it a bit for my own purposes. The plush was hand sewn and full of plastic beads to make it floppier. I feel that this design choice worked out well as it makes it perfect to be situated on the shoulder.

Process: Electronics
The circuit features a voltage divider with a pressure sensor attached to it.The whole circuit isn’t placed directly on the plush, instead  it is sewn onto a Black Spandex “housing”. The rest of the electronics are housed in the circuit playground.

Road Runner – Angelina Do (#3182746)

Project Title: “Road Runner”

Project Description

“Road Runner” is a wearable electronic exhibited in the form of a baseball cap. “Road Runner” is a wearable created for runners who like to train on the street (especially those who like to run at night). This wearable is meant to act as a safety tool, allowing the user to signal drivers which way they are running/turning to avoid any potential accidents. This project is inspired by my own passion to train and run in the late evenings.

This hat is an interactive experience allowing the user to activate programmed sensors based on their movements. This wearable allows the user to set off the left strip or right strip of flora neopixels by tilting their either head left or right. In addition, a built-in safety function has been implemented, when the wearable reaches above 30 Degrees Celsius, the lights are programmed to turn off to avoid over heating of the device. The sensors used in this project include the onboard accelerometer and temperature sensor.

This wearable consists of two different lighting modes to display the following:

  • Tilt Left: Left half of on-board CPX neopixels glow pink, while left strip of implemented flora neopixels flash pink and yellow.
  • Tilt Right: Right half of on-board CPX neopixels glow pink, while right strip of implemented flora neopixels flash pink and yellow.

“Road Runner” is also accompanied by a start-up animation and chime to alert the user the wearable has been turned on.

  • Lessons learned/next steps

I had the absolute worst luck while completing this assignment. I went through 4 bobbins of 30 ft conductive thread, and I learned that I should always buy way more than anticipated to save me the commute down to Creatron Inc. I also learned to be extremely careful when tying off the ends of the circuits, I ran into the issue of tying too tight, causing the thread to snap. I had to redo this entire soft circuit about 8 times now, and I definitely learned my lesson of patience and resillience. Some next steps I would take is maybe printing translucent 3D cases for the neopixels and CPX to add an extra layer of protection from heavy usage.




Masks On


Masks On is a wearable tech project that transforms what has been a necessity for the last two years – masks.

Masks have been a utility. There are a protective barrier between ourselves and the world, and upon its wearer, grants significant anonymity. Behind the mask, it is easy to escape and become lost in the crowd.

Masks On combats this notion to conceal identity. Using the sound sensor, accelerometer sensor, and neopixels imbedded inside the Circuit Playground, ones presence as captured in motion and vocality are animated. When the user talks, a randomly generated number of  neopixels will light up at a brightness proportional to their loudness. Furthermore, as the user tilts their head, the neopixels will only light up on the opposing side. The circuit board intimately responds to the wearer’s body and spirit, amplifying and projecting them into the world.

Parts List:

  • 1 x Circuit Playground Express
  • 15 inches x Conductive Thread
  • 1 x 3.5V Battery Pack
  • 1 x Cloth Mask

Project Context:

This mask by Mask Market has a very similar concept of responding to the user’s vocal presence. It uses a LED Matrix to simulate the user’s mouth as a smiley, opening and closing when the user talks. This design is definitely more literal. It’s fun and not meant to be taken too seriously.

Most comparable masks I found used fibre optics to light up the face. I think they’re aesthetically pleasing although a bit uninspired. These masks also don’t include a reactive component with sensors.

Final Thoughts:

Overall I’m really pleased with my project. It’s worth noting that my interests in wearable tech are driven by fashion, so when approaching this project it was important for me to make something aesthetically intriguing. I love the juxtaposition of nature with technology. It’s a dichotomy I frequently explore in my work for its ability to transform technology’s role into something much more metaphysical.

In all seriousness, creating this project was a culmination of thoughts around how to explore our subconscious movement patterns. As I spend more time in a computer chair and isolated from a social environment, I’ve noticed increased back pain and jaw tension. By applying the principles of “Where to Wear It” by Clint Zeagler, the goal was to create a wearable that brought attention to physical positioning and habit forming.

The Micromanager
The Micromanager

Through capacitive sensing, I built a wearable that links physical movement to immediate feedback through sound and light.

Step 1: Supplies


Creating a bite sensor was an experiment of materials. I was running all over walmart trying to think about how I would create something that offers good “chewability” but would also be able to keep out any unwanted water from the electrical components. I also needed to figure out how to properly insulate the stainless steel thread that I would be using to connect my sensors to the CPX and battery pack.

So, I landed on a mouthguard and baby bib for the bite sensor. And some good ol’ fashioned yarn to loop around the thread. Although that took some serious trial and error to figure out the best knot method.

I also had to build a little pouch to contain the CPX and battery pack. So I made a trip to The Workroom and grabbed a few pieces of fabric.

Step 2: Sensor Assembly



Using Velostat and conductive fabric, I created a bite sensor. First thing was to create a platform that the fabric could rest on. Using hot glue, I created an even layer and placed the fabric on it. Then I built up a layer around the fabric to make sure that there was no way the signal could go around the velostat. Other than the glue fortifications, the rest of the sensor went as expected.

Final Sensor Outcome:


The seat sensor was created in the same way by sandwiching together the velostat and conductive fabric.



Step 3: Circuity

circuit-1 Starting with stainless steel threads, I attached them to the CPX and planned out how they would be attached to the sensors (aka: length and pin location)circuit-2 circuit-3


Next, I practiced my friendship bracelet knots! After a few failed attempts at making other knots, this turned out to be the quickest and least likely to tangle.



Attached to GND is my capacitor. I looped it through the pin then tied a stainless steel thread to the other end. I also wrapped the entire component up in yarn.




I was still worried about the wires crossing, so I brought out the shrink wrap and colour coordinated it. Less confusing overall.





Step 4: Component Pocket (aka: the feed bag)

bag-1 bag-2 bag-3 bag-4 bag-5







This is pretty straightforward. My first prototype was on paper, but I recycled it before snapping a photo.

I decided to use fabric glue instead of sewing.. I lack both the patience and time to hand sew. It’s a work in progress!

Step 5: All together now

As I was digging around, I found a wearable that similarly explores sending reminders and analytics of proper posture.

Khalifa- Fast Push-ups?

The concept behind this idea was to have a device that could help you prevent doing workouts the wrong way. In the heat of the moment, many people tend to forget the rate they are supposed to be going at in order to get the best possible workout. So this wearables is a device that tells you if you are going too fast on your push-ups it will help you going at the perfect rate for a better workout.
You will first have the device tied around your waist, and as you go up and down, If the device was to make a sound and turn red, it means you went too fast and on the other hand if you were to hear nothing you are able to keep going at that rate and so on.

Wearing the device:

In use photo and design choice:

Incorporating it with your training belt will help you manage your comfort and space accordingly. I thought of the Idea of making it vibrate instead of showing the lights because it wouldn’t really help the user by have the nonpixel. So sound and vibration would be the perfect combination for this device.


Colour Matching Hat – Valeria Suing

In my last project, I explored the theme of colour as a self-expression tool. With this project I wanted to further that experience by giving the user more freedom on choosing which colour to use. The hat has 6 NeoPixels attached along the under brim and using the light sensor allows the user to match the colour of their choice. Additionally, as a way to protect the wearable, I used the temperature sensor which will alert the user when the circuit is getting overheated.

Project Context

I was really inspired by this project from Kieun Kim. She uses lighting and movement to explore self-esteem, human connections and aesthetic emotions. The quote “I want to reveal myself through the intensity of illumination” really inspired me to keep exploring this theme.

A great resource from Adafruit was this Chamaleon Scarf, it served me as a very useful guide during the construction process.

Design Choices

I made a choice to use cotton to diffuse the NeoPixels. I liked the effect the cotton gave to the lights, and it was also a way to hide the circuit and protect the conductive thread.

Next Steps & Lessons Learned

This project really pushed my sewing skills, now I feel more confident working with conductive thread. I liked exploring soft circuits and ensuring a comfortable and light wearable. If I could continue with the design of this project I would like to find a way to integrate a battery into the hat and make the cotton less visible from the outside. In terms of coding, I would like to integrate motion and control the behaviour of lights according to different head gestures.


Audioreactive glove by Atharva Jadhav



I love things that react to audio. I believe audio gives the most dynamic and interesting set of data values compared to any other sensors since audio is capable of perceiving music and music and come in various patterns and rhythms. For this project, I wanted to play around with the MEMS microphone audio sensor inside the Adafruit Circuit Playground Express and create an audio-reactive piece of fashion. I wanted to create something that can be perceived as divine in an alien sense of way.


I created a useless machine, an audio-reactive glove that uses the capacitive sensor to activate when one cups their hands like above or makes any gesture that makes use of the ring finger. This useless machine serves as a party accessory or is a piece of cyberpunk fashion.

How it works is when one touches the ring finger of the glove, they touch the alligator clip attached to the ring finger and their hand which feeds data into the capacitive touch sensor A1. The further you are from touching the alligator clip, the closer the values detected by the touch sensor are near zero. Once the sensor detects a significant value, the microphone starts to detect and store the sound values, these values or in turn used as values for the RGB colors of the onboard neo-pixels with a few parameters. this results in- low audio level corresponding to cooler hues and high audio level corresponding to warmer colour hues. Use this love to give yourself and your friends a little party.

Motion Controlled Color Sound Level

The general concept of this project was to create a LED display of sound levels in the room for a deaf or hard of hearing person to wear on their wrist in order to give them more awareness of the surroundings. (A scenario like a deaf parent wanting an indicator if there baby starts crying, or a fire alarm going off)

The wearable is the Circuit Playground Express displayed on a watch where the amount of LEDS on increases as microphone picks up sound level increase. Controlled with the accelerometer.

You turn on the display when you rotate your wrist 90 degrees and back, from there the first colour is bright red for when the user is really using it and wants a bright and alert LED colour to respond to. If you rotate your wrist again the colour changes for a more sensitive and responsive sound indicator and then again for a third colour that is less sensitive and then off again. These colours can be programmed by the user for more personal colours or ones they want displayed. You can also rotate your wrist the opposite way to go back to the previous colour (or state).

This article talks about how lights can be used to indicate direction and level of sound cues for dead people.


It is a very simple design with nothing but the Circuit Playground Express but I started off creating the LEDS reaction to the level of sound, as sound level increases so does the amount of LEDS that are on in order. Then experimenting with the accelerometer to see what values I needed to work with for the flick response and it turned out to be the X values so I then coded the response to when the user flicks there wrist in either direction. Which turned out to be an X value of 10 and -10 with the normal X position being around 0. For next steps I want to add additional functionality like changing from sound indicator to light indicator when you flick your wrist in a specific way and then again changing to a colour sensor.

Automated Sunglasses-Sam Kingston

Automated Sunglasses

For this assignment, I wanted to make a useless machine. I decided to use photo resistors on the front and back of a balaclava to sense when the wearer is facing the sun. Using a servo which pulls a string attached to the bottom of clip-on sunglasses, the glasses flip down more light is sensed on the front than the back. I was inspired by the look of the homemade suits form the spider-man movies which is why I opted to mount the servo on the back out of view instead of just on the side with an arm directly attached to the sunglasses which, in hindsight, would have worked way better. I designed sewable parts to guide the tubing which were printed in water-washable resin on an Elegoo Mars 2 Pro.  Images of the final product can be seen below. Aesthetically, I think I got where I wanted. The design looks absolutely ridiculous which, I think, matches how ridiculous the concept is perfectly. My original plan was to connect the front photoresistor to the arduino using conductive thread but after seeing the tubing I though it would be more visually interesting to use wires mounted next to the tubing which is the direction I took. The tubing was crucial to eliminate friction on the fishing line I used in order to let the glasses drop back down seeing as they’re incredibly light and without an active force pushing them back down, gravity was doing all of the work. In the end, it didn’t work perfectly. I think that this is largely due to my inability to get perfect tension on the servo arm. Since I had to reach back and tie it to the servo myself, I think there’s a little too much slack in the line. This causes the glasses to raise properly but they can’t quite get all the way back down. The glasses would also benefit from some added weight which would absolutely be the next step to get them working consistently. Because of this, you’ll notice that in the video linked below the images I have to give it a bit of help by pushing them down the last few millimeters. With a little more time I know that this could be remedied!



For this demonstration, I set the glasses to raise and lower every 3 seconds instead of responding to the light. This was to help be get a clearer video to better show the actual movement because I couldn’t show it well when filming on my own and moving around to change the light source. I promise the code works and can take another video if necessary!
