Wearable Sensor Network for Body Kinematics Monitoring

A comfortable wearable sensor network for monitoring the body kinematics during hidrocinesiotherapy sessions is presented. Sensing modules composed by 3-axis accelerometers, 3-axis magnetometers and interface electronics are integrated in a swimming suit and connected to a microcontroller by a serial interface. Data from the suit is transmitted to a base station using a 2.4 GHz RF transceiver. Temperature, heart rate and frequency rate are also monitored by the suit, and the sensor network presented can distinguish between rotation and motion of the monitored system. Each sensing module presents a 1 degree resolution.
