Step 3: Prototyping
We sketched and created functional prototypes that included vibration motors, then iterated upon them after testing and research. This was done with an addition of a heating element into the system to soothe the muscle.
Description
Creating TremSleeve involved developing multiple prototypes to test the effectiveness of the mechanical vibrations and implement an overall more effective power supply in the sleeve itself. This entailed material selection, prototype development, and integrating new features within it, such as a heating element to soothe the muscles. We did some research into anatomy, particularly of the forearm (antebrachium), and took courses on muscle movement which helped us place components optimally.
Working out closely, in conjunction, was how the motors and sensors work together to provide the desired tremor reduction.
Steps
- Material Selection: The sleeve was modelled into two different materials, after which we settled on a more stretchy fabric for comfort and fit.
- Prototype Development: Developed four slightly different prototypes and examined endless ways to place the circuit components such as sensors, motors, heating elements, and switches on the forearm to ensure the best functionality and user comfort.
- Motor and Sensor Integration: Integrated vibration motors that provide dynamic vibrations to counteract tremors; sensors to detect and record tremor frequency. Real-time vibration intensity would be self-adjusting based on the sensor data.
- Heating Element Addition: Added a heating element to calm the muscles down and enhance comfort for the user.
- Zipper Prototype: Created a prototype with a zipper to make the sleeve easier to wear and remove.
- Power Supply Integration: Having a small cell inside the sleeve was considered best in relation to portability and user convenience.
