WOSNA

The WorkOut Sensor Node Assistant (WOSNA), a body sensor net composed of many tiny sensor nodes that can suck on the skin.

The WOSNA uses pulse sensors to monitor muscle contractions. The pulse sensor can detect the change of blood flow in the muscle caused by contraction, and send data back to the central device by Bluetooth Low Energy (BLE). The program running on the central device can use the data to monitor the performance of the workout. Including how many sets of motion you did, if the motion is standard and if you are using other muscles for compensation.

WOSNA detects muscle contractions.

This project is still in an earlier phase, and more details are to come.
