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.

Description

technical field [0001] The disclosure belongs to the field of sensing technology and self-driving technology, and relates to a friction nanogenerator, a self-driving vector and direction sensor and a system. Background technique [0002] With the rapid development of smart terminals, mobile networks and smart Internet of Things, the performance requirements of sensors are constantly improving. The principle of traditional sensors is mainly based on technologies such as light waves, electromagnetic waves, piezoelectricity, and capacitance, and has excellent performance in terms of sensitivity, stability, and linearity. As the number of sensors increases, the overall power consumption of the sensors increases dramatically, and these energy sources are often provided by external batteries. However, batteries need to be recharged, replaced, and recycled frequently. Therefore, finding a sustainable energy source to build self-driving sensors is a major development direction for ...
