Measure your foot acceleration

Some embedded projects look really crazy and fun. And even these can have a practical issues. This is one of Cornell University students project where they put acceleration sensor on a foot to measure its acceleration during walking, running and sport activities. They used a Kionic KXSD9-2050 three-axis accelerometer, XBee wireless transmitter, and an ATmega324P microcontroller. So transmitter sends measured acceleration data along with time values where it can be viewed in Matlab.

As a result they’ve been able to send x,y, and z acceleration values and display it on Matlab graphs. When you have data in your computer this is up to you what analysis are you going to do in order to emit indicators showing where sportsman had too strong football kick what means injure risks or other effects. Accelerometers on a shoe or hand can be used for more exiting purposes like perfecting arm motion in bowling, baseball etc. Anyway this is a great project where you can get some skills in wireless data transmission, acquiring data from accelerometer and interfacing microcontroller to Matlab via RS232 interface.

  1. hey… i recently tried to do this but my outputs arnt getting recorded in the pc matlab.. has any1 got this workin.. if so can any1 give a small guide or help

  2. Hi pamod .
    Im also trying to make the same accelerometer. Need little assisstance with the pcb layout. Slightly urgent.

    Waiting for a response
