Kind Code:
A1
Abstract:
A signal detection sensing structure, comprising: a first piezoelectric electret layer (1), a second piezoelectric electret layer (2), and a bonding layer (5) arranged between the first piezoelectric electret layer (1) and the second piezoelectric electret layer (2). The first piezoelectric electret layer (1) comprises on the surface thereof on the side facing away from the second piezoelectric electret layer (2) multiple protruding structures (3). The surface of the side of the second piezoelectric electret layer (2) in proximity to the first piezoelectric electret layer (1) is a smooth surface. The first piezoelectric electret layer (1) is configured to detect at least one of a contact signal and a sliding signal of a touch object. The second piezoelectric electret layer (2) is configured to detect the contact signal of the touch object.
