A wireless platform implementation for biomechanical data analysis

The analysis of motor skills and technical gestures in sports guide to the understanding of the biomechanics of the human body. There are many complex interaction mechanisms between body and environment, due to the intrinsic dynamic characteristics that come along with these activities. To understand the above mentioned, we need to have different measurement tools that allow us to know in detail the human body movements. In this work we describe an implementation of a wireless platform for biomechanical data analysis. This allowed us to measure characteristics of natural movements of daily life, as well as a specific activity as “karate techniques”. We used four different sensor for the analogic measure: pressure sensor, gyroscope, accelerometer and electromyography electrodes. We distributed each sensor in significant measurement points that are characterized and synchronized with a computer. Also, we designed a graphical interface based on virtual instrumentation in order to have relevant data analysis. Results show the operation and graphics generated during some trials with sensors and the graphic interface developed.
