Abstract
Disclosed is an integrated physiological signal detection sensor, comprising a movable housing member, a fixed housing member, and a sensing unit circuit board. The movable housing member and the fixed housing member are connected to form an internal space therebetween. The sensing unit circuit board is fixedly installed on the fixed housing member within the space. A piezoelectric film is attached to the sensing unit circuit board. A hollowed-out region surrounds the periphery of the piezoelectric film. A protrusion is provided on the movable housing member at a position corresponding to the piezoelectric film. The sensor of the present invention has advantages of simplified sensor installation, improved signal integrity, and simplified wire routing of an electromagnetic shield layer, thereby eliminating errors caused by sensor installation and improving the accuracy of data detection.
