Title:

SENSOR AND POWER GENERATOR BASED ON ELECTROSTATIC INDUCTION, AND SENSING METHOD AND POWER GENERATION METHOD

Document Type and Number:

WIPO Patent Application WO/2015/158302

Kind Code:

A1

Abstract:

A sensor and a power generator based on electrostatic induction, and a sensing method and a power generation method thereof. A sensing member of the sensor consists of a first electrode layer (2) and a matching second electrode layer (3), and the first electrode layer (2) and the second electrode layer (3) are spaced from each other and are electrically connected. The sensing member and a detected object (1) are integrally formed to obtain a power generator. When the detected object (1) moves relative to the first electrode layer (2) of the sensing member, the potential of charges carried by the sensing member on the first electrode layer (2) changes, and the charges flow, under the effect of electrostatic induction, between the first electrode layer (2) and the second electrode layer (3) to form a current. The sensor has a simple structure and does not need an external power source.
