Abstract

My project focuses on developing a wrist and hand-worn device that helps in injury rehabilitation. It features a traffic light system to alert users if they are exerting too much pressure on the area. I came up with the idea for this device since I have had issues with wrist pain for the last three years. This device helps prevent further strain or injury by providing a simple visual cue: green for safe pressure, orange for caution, and red for excessive pressure.

I explored various options for building this device and discussed my idea with Neil Weldon, who has a background in Computer Science, to refine my idea. I sourced components which included various pressure sensors and LED lights, which form the traffic light system and a programmable microcontroller. Through experimentation, I evaluated the effectiveness of each pressure sensor to determine the best one and how to integrate them. I did extensive research on the anatomy of the arm, wrist, and hand along with different conditions and injuries.

I interviewed several professionals in their field (biomedical engineer and physiotherapist). I calibrated the device to multiple people to gain data on how the device will work for different people depending on age and gender. I conducted a survey to gauge public interest. I asked participants about their injury history and whether they would use the device during rehabilitation. I analysed this data through SPSS software. In conclusion through experimentation and evaluation, I found that my device could have a benefit.
