Embodiment Construction

[0039] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that in the drawings or description of the specification, similar or identical parts use the same drawing numbers. The implementations not shown or described in the drawings are those known to those of ordinary skill in the art. In addition, although this article may provide an example of a parameter containing a specific value, it should be understood that the parameter does not need to be exactly equal to the corresponding value, but can be approximated to the corresponding value within acceptable error tolerances or design constraints. The directional terms mentioned in the embodiments, such as "upper", "lower", "front", "rear", "left", "right", etc., are only directions with reference to the draw...

Abstract

The invention discloses a generator based on an asymmetric dielectric layer and a power generating method. The generator comprises an electrification layer, a first dielectric layer, and a second dielectric layer, a first electrode layer and a second electrode layer. The first electric layer and the second dielectric layer are arranged at the lower surface of the electrification layer in contact; and the first electrode layer and the second electrode layer are arranged at the lower surfaces of the first dielectric layer and the second dielectric layer respectively. When a contactant with the different surface electron gaining-losing capability is in contact with or separated from the electrification layer or slides, different dielectric layers modulate electric fields generated by surface charges of the electrification layer and a potential difference is formed between the first electrode layer and the second electrode layer, wherein the potential difference can drive electrons to form currents when an external circuit is connected. When the mechanical energy is converted into the electric energy, power generation can be realized without any relative motion between the two electrode layers, so that packaging of the generator and matched application with other devices can be realized well.

Description

Technical field [0001] The present invention relates to the field of energy conversion, in particular to a generator and a power generation method that utilizes the dielectric properties of materials to convert the mechanical energy of contacting objects into electrical energy. Background technique [0002] Friction is a common phenomenon in nature. Since 2012, it was proposed to use different materials to contact frictional electrification to collect mechanical energy in the environment and convert it into electrical energy. It has attracted widespread attention due to its unique advantages. Generators that use material contact triboelectric effect and electrostatic induction effect can convert mechanical energy in the environment, such as body sliding and clothing contact, into usable electrical energy. However, at present, the positive and negative electrodes output by most generators belong to two separate parts, which is not conducive to the packaging and implantation of the...
