Improve Reliability

In this paper, a new contact-pin type pulse transducer is designed to improve reliability of the pulse-waveform acquisition. The transducer contains two pressure sensor dies with two contact pins on the top, a wire-bonded circuit board, and power driving mechanism. The designed contact-pin is firmly supported by a thin membrane on the package of the transducer. It can minimize the friction for vibration measurement and can easy adjust misalignment for long-term physical measurements that can be used to accurately extract more pulse information by measuring pulse waveforms from the wrist artery. Some special apparatus designed as fixtures have been setup for the transducer fabrication and applications. Experimental results show that the designed contact-pin transducer is robust and feasible for further applications.
