A wrist-worn health monitoring terminal is developed to realize body's multi-parameter measurement by including a common mobile phone. The common mobile phone wireless connected to the health monitoring terminal is included to be the memory and the displayer. Also the mobile phone acts as the wireless module to communicate with the health service centre. The physiological parameters includes body...
A prototype microsystem is presented for wireless neural recording application. An inductive link was built for transcutaneous wireless power transfer and data transmission. Total 16.5 mW power and 50 bps - 2.5 Kbps command data can be received over 1-5 MHz with a distance of 0-10 mm. The integrated amplifiers were designed with a limited bandwidth for neural signals acquisition. The gain of 60 dB...
An indoor wireless communication system using off-the-shelf white LED was presented in this paper. We adopted OOK (On-Off Keying) modulation in transmitter module. Data transmission was realized based on RS-485 protocol. A DC-balanced coding with error check and correction abilities was applied to avoid blinking and improve the performance of the system. The system can keep 10-7 error bit rate within...
A group of prototype integrated circuits are presented for a wireless neural recording micro-system. An inductive link was built for transcutaneous wireless power transfer and data transmission. Power and data were transmitted by a pair of coils on a same carrier frequency. The integrated receiver circuitry was composed of a full-wave bridge rectifier, a voltage regulator, a date recovery circuit,...
