Project Summary:

ATTRACTS is a DIY smartwatch to prevent the carpal tunnel syndrome. It also can be used to exercise by people who have a muscle weakness and people who had stroke recovery.

Full Project:

ATTRACTS is made of some electronic modules. ATTRACTS has Teensy 3.1 for its microcontroller. ATTRACTS has a TFT 1.44” LCD Screen. Furthermore, ATTRACTS can be used as a mouse because it has Bluetooth HID module and gyrometer as its direction of movement. ATTRACTS uses 3.7 Volt battery as its power supply. Here is the picture of ATTRACTS.



We use 3D printing for its case. We made the case with a software called Sketch Up. We use Straps cloth as its wristwatch



ATTRACTS uses 2 sensor to detect the hand movement, flex sensor and module muscle sensor. The flex sensor is attached in the gloves, and used to exercise and diagnose the carpal tunnel syndrome through the movement of the thumb. In the module muscle sensor, there is a 9 volt battery as its power supply.

About attracts

We are ATTRACTS team, we come from Indonesia. We have create a project about medical watch by using Teensy and Arduino. One of the parts of the watch can be used as a mouse so if you need a mouse, just use the watch :D
