Biometric information sensing device

Abstract

A biometric information sensing device for attaching to a body surface of a biological body for sensing the biometric information such as heartbeat, respiration, positioning, or body movement includes at least one piezoelectric layer having piezoelectric conversion function. The piezoelectric layer includes at least one bending portion and at least one adhesive portion, wherein the adhesive portion is directly or indirectly attached to the biological body to sense deformation of the surface of the biological body and the bending portion enhances the deformation to transform into an electrical sensing signal to transmit to a circuit broad, via signal processing and transmits to a remote control unit for analyzing the biometric information of the biological body. The sensitivity is enhanced by the bending portion of the piezoelectric layer to improve signal-to-noise ratio.
