Flexible printed pressure sensors possess great potential advantages for wearable and disposable healthcare applications such as a patch-type pressure sensor. In this study, we demonstrate a newly developed flexible printed pressure sensor consisting of a ferroelectric polymer layer and organic thin-film transistors (OTFTs) on a plastic film substrate in order to monitor the human Pulse Rate and Pulse Wave Velocity. We estimated the ability of the printed sensor as the amplifier, and found an amplification factor of 10.To monitor Pulse Rate and Pulse Wave Velocity, the sensor was attached to the wrist and neck of a volunteer using a skin-compatible adhesive patch.The sensor clearly detected the human pulse rate and Pulse Wave Volcity.
