FRICTION NANOGENERATOR, AND SELF-DRIVEN VECTOR AND DIRECTION SENSORS, AND SYSTEM THEREOF

Document Type and Number:

WIPO Patent Application WO/2020/098280

Kind Code:

A1

Abstract:

A friction nanogenerator, and a self-driven vector sensor and a self-driven direction sensor, and a system thereof. The friction nanogenerator comprises: a first friction unit (100) comprising a first friction layer (101); and a second friction unit (200) comprising a second support layer (201), a second friction layer (202) provided on one surface where the second support layer is in contact friction with the first friction layer, and a charge collection layer (203) provided on at least one side surface of the second support layer adjacent to the second friction layer, and having an air gap with the first friction layer and a distance from the second friction layer, wherein the charge collection layer and the second friction layer respectively serve as electrical output ends of the friction nanogenerator. The generator implements direct conversion from mechanical energy to direct current electrical energy, without the use of an additional power management circuit, so that circuit design is simplified. The sensors can be used for monitoring information such as the speed, acceleration, displacement, angle, frequency, and rotational speed of a moving object, and can perform real-time tracking and imaging on a motion trajectory.
