In this paper, we developed a novel motion capture system with multi-sensing-node based on inertial MEMS sensors and ZigBee network, which is expected to be performed ubiquitously, not only strictly used in particular room as optical capture system does. First, the multi-node motion capture system was defined, which can track human motions and postures simultaneously and wirelessly. Second, multi micro inertial measurement units (uIMU) were designed by integrating the inertial MEMS sensors, micro controller unit and ZigBee module. At last, a wireless multi-sensing network was built up. Experiments showed that the sampling rate of this system was 50 Hz. The further work will be focused on the amelioration of ZigBee protocols for faster sampling rate of multi-node system, as well as human motion tracking algorithms.
