HealStrap
The task was to select an existing sports product and enhance its functionality by integrating electronic technology to improve the user experience and performance.
I chose to focus on an ACL knee brace because ACL injuries are a common and serious sports injury, particularly in high-impact and pivoting sports. Recovery can be long and challenging, so I wanted to explore how existing knee braces could be improved through the integration of electronics to better support athletes during rehabilitation and their return to sport.

Testing
For the testing stage, I used fabric prototypes to test the design and gathered feedback from classmates, people with ACL injuries, and medical professionals.

Final
For the final design, I integrated all the internal electronics, ensuring the wiring was protected while allowing the components to be easily removed for washing.
Final Design
Adjustable vibration sensors – positioned over the ACL area to provide targeted vibration intended to support recovery.
User-controlled activation – a button allows the user to switch the vibration feedback on when needed.
Pressure monitoring – maintains consistent pressure around the knee and detects when the brace becomes too loose.
Warning light – alerts the user when the brace loses the required pressure or fit.
Locking side supports – hinged sides can lock at set positions to control knee bending and encourage more conscious movement.
Washable electronics – internal components can be removed, allowing the fabric brace to be washed.
Protected wiring – all wiring is concealed within the brace for comfort and safety.
