    摘要: A sensor (100), comprising: a sensing assembly (110), the sensing assembly (110) comprising a sensing piezoelectric layer (111) and a sensing electrode layer (112); a frequency adjustment assembly (120), the frequency adjustment assembly (120) being physically connected to the sensing assembly (110), and the frequency adjustment assembly (120) deforming under the action of an electrical signal, so that the sensing piezoelectric layer(111) deforms, so as to change the resonance frequency of the sensing assembly (110); and a substrate (130), the substrate (130) being used for carrying the sensing assembly (110) and the frequency adjustment assembly (120).
