More Information
Summary:The present invention discloses an optical fingerprint sensing device with biomedical sensing functions, which mainly comprises at least one light emitting component for generating a light source and an image sensing module. The image sensing module is provided with a plurality of sensing units capable of receiving a light source reflected through a finger in a normal fingerprint sensing mode, and transmitting a measured brightness signal so as to obtain a fingerprint image. The image sensing module is further provided with a partial area therein, so that part of the sensing units of the sensing units are located in the partial area at the same time, and the sensing units located in the partial area are electrically connected through a first switch to perform in a biomedical sensing mode, and measure light intensity signals of a finger, in turn, variations in time domain of the light intensity signals are used as photoplethysmography (PPG) signals for subsequent biomedical applications.
