This paper describes the development of a telemetry system for measuring human movement. The telemetry system consists of a transmitter and a receiver. The transmitter, with two vibrating gyroscope sensors, band-pass filters and PWM-FM modulators, was put on a body to measure front-back and right-left head movements. The receiver, with Schmitt trigger circuits and low-pass filters, was demodulated from digitized transmissive signals to analog signals. From experimental results, noises on received signals were eliminated ; the waveform of the received signal was equal to that of the output signals of the sensor. The system is compact, portable and available outdoors because the system is driven by batteries. Finally, we consider the possibility of applying this system to evaluate rehabilitation effects.
