Abstract A wearable WIMU (Wireless Inertial Measurement Unit) [1] system for sportsapplications based on Tyndall's 25mm mote technology [2] has been developed to identifytennis performance determining factors, giving coaches & players improved feedback [3, 4].Multiple WIMUs transmit player motion data to a PC/laptop via a receiver unit. Internally theWIMUs consist of: an IMU layer with MEMS based sensors; a microcontroller/transceiverlayer; and an interconnect layer with supplemental 70g accelerometers and a lithium-ionbattery. Packaging consists of a robust ABS plastic case with internal padding, a power switch,battery charging port and status LED with Velcro-elastic straps that are used to attach thedevice to the player. This offers protection from impact, sweat, and movement of sensorswhich could cause degradation in device performance. In addition, an important requirementfor this device is that it needs to be lightweight and comfortable to wear. Calibration ensuresthat misalignment of the accelerometer and magnetometer axes are accounted for, allowingmore accurate measurements to be made.
