Application of MEMS to biologic system mainly categorized into bio-electronics and micro-medical systems, Bio-electronics concerns on the biocompatible electronic device, in-vivo sensors, the sensors based on biological materials, biological materials for electronics and optics, the concepts and materials Inspired by biology and useful for electronics, the algorithm inspired by biology, artificial sense, and the biologic-inorganic hybrids. Micro-medical systems are utilited into the drug delivery systems, micro patient monitoring systems, micro prosthesis and artificial organs, cardiology related prothesis, analysis systems, and the minimal invasive surgery tools based on the m icrom achining technology.

In this paper, we implement a portable photo- plethysmography(PPG) measurement system using PDA. The developed system is composed of sensor unit, signal acquisition unit, and PDA. The sensor unit consists of photo transducer and detects the volume pulse at finger tip capillary. The signal aquisition unit includes signal processing part, A/D convertor, and 8051 based microcontroller. After analog signal processing, the volume pulse is converted to 12 bit data by A/D convertor. PDA displays and stores the l2bit data transmitted from 8051 based microcontroller.
