Flexible printed amplifier circuits are needed in wearable sensors realization sensitivity enhance, for applications in various fields of healthcare. Here we show a highly sensitive printed pressure sensor with low operating voltage (-3 V) and their application for monitoring a human Pulse Wave Veracity (PWV). A printed sensor consisted of 2 µm-thick pressure detector and an organic amplification circuit were simultaneously formed on flexible substrates. The printed organic circuit can amplify a generated signal by gain factor of 10. Our sensor can easily monitor human vital sign of PWV to estimate health conditions on state of attaching the skin.
