碩士 === 國立臺灣科技大學 === 電子工程系 === 96 === The main subject of this paper is to detect the ECG R wave by using only two uniploar leads and the wireless transmit the heart beat pulse by 5.5KHz frequency. Due to the non-coded transmittion each heart beat will occur a 5.5KHz radio frequency radiation to the receiver side, the receiver receives the radiation pulse then form as a square wave for console calculation to count the heart rate value. By the experiments found that the textile chest belt design could have more stable heart signal pick-up, more comfortable for long-time wearing so that more suit for the using of sporting purpose. The detail analysis and considerations for each section of the system such as the pair resonation of conductance and capacitance design and the sponge added under the receiver module PCB board as a damping effect which can reduce mechanical vibration which makes the system more reliable. The results of the study founds as an application for treadmill wireless transmittion purpose , 5.5KHz radio frequency still is the competitively chose .
