Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0026] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the relationship between the components in a certain posture. If the specific posture changes, the directional indication will also change accordingly.

[0027] In addition, if there are descriptions involving "first", "second" and so on in the...

Abstract

The invention provides a power generation film, which comprises a positive electrode layer, a negative electrode layer and a piezoelectric electret film, wherein the piezoelectric electret film is clamped between the positive electrode layer and the negative electrode layer. The piezoelectric electret film comprises a plurality of composite fibers distributed in a random network manner, wherein the composite fibers comprises electret fibers and a zinc oxide film wrapping the periphery of the electret fibers. The invention further provides a wearable device with the power generation film. Whenexternal acting force causes mechanical deformation of the power generation film, the space position of the zinc oxide/electret composite fibers of the random network structure changes and the extrusion between the fibers occurs, so that a great induction voltage and an induced current are generated, and high-efficiency electric energy output is realized through the positive electrode and the negative electrode. The power generation film is applied to the wearable device, and long-term uninterrupted power supply for the wearable device can be realized.

Description

technical field [0001] The invention relates to the technical field of electronic devices, in particular to a power generation film and a wearable device. Background technique [0002] A wearable device is a portable device that is worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not only a hardware device, but also achieve powerful functions through software support, data interaction, and cloud interaction. Wearable devices will bring great changes to our lives and perceptions. Among them, the power supply problem is a key technical problem currently faced by wearable devices. Existing wearable devices are usually powered by rechargeable batteries. When the battery power is exhausted, the user needs to charge it again to use it normally, and cannot provide uninterrupted power supply for a long time. Contents of the invention [0003] The main purpose of the present invention is to propose a power generation film and a...
