A Portable System for Measuring Human Body Movement

A low cost portable acquisition system for monitoring and processing human body segment movements is presented. It is equipped with 32 multiplexed input channels, each one linked to an external 2 axis MEMS accelerometer. Input signals from sensors are converted into a digital form by a 10 bit analog to digital converter and transmitted via Bluetooth technology to a remote PC. The instrument is battery powered and then it can be used in applications like ergonomics, rehabilitation and sport medicine. Labview 7.1 has been used to visualize in real time the human body segment movements.
