| Summary: | 碩士 === 國立臺灣科技大學 === 電子工程系 === 99 === With the wealth of society and progress, everyone in the rich material life conditions caused by the weight straight up modern, but also caused the rapid increase in cardiovascular disease patients and younger. Therefore, some portable medical electronic equipment if standing at home so that users can always check your body. In addition to early detection of problems that may save lives, but also can reduce the emergency or to the hospital like the social costs. Coupled with today's electronics industry, the technological breakthroughs and advances, which makes low-cost high-precision medical electronics equipment possible to achieve. And only low-cost high-precision devices is possible a lot of popularity.
In this paper the study of low-cost high-precision portable ECG machine and implementation of related technologies, technology will power-level film made from the skin surface through a weak differential signal after filtering and amplification process can be complete ECG waveform, At the same time by the MCU in a / D conversion via the LCD output to user-friendly interpretation of observed or measured ECG waveform. The entire system from a single 5V battery supply can be completed.
