To validate my second year in my engineering school I had to make an internship abroad. So, I decide to go to the University of Plymouth in England !
The topic of my internship is to develop a smart bracelet for runners. On this bracelet, there is a GPS, accelerometer, gyroscope, compass, li-po charger, bluetooth, EEPROM and ECG sensor. All information are saved in the EEPROM during race and when you arrive in your house, you can upload all the information on your tablet. You will be able to trace some graph and the route on google map that you have made.
This is some rendering with Solidworks:
