Abstract
To detect human body vital physiological signals, an electrochemical wearable sensor and a single-mode artificial mechanoreceptor have been developed and their capabilities to detect cardiorespiratory signals, as well as to detect rapid adaptive and slow adaptive responses have been preliminarily demonstrated. The electrochemical method based on I-/I3- redox couple proves to be a sensitive transduction mechanism. Furthermore, a common gate transimpedance amplifier based on gallium nitride high electron mobility transistor for the mechano-acoustic sensor and the wearable mechanoreceptor was developed. The transistor’s performance at high temperatures has been investigated, and its failure mode at high temperature has been discussed.
