Embodiment Construction

[0044] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0045] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to t...

Abstract

The invention relates to a tactile feedback electrode and a preparation method thereof, a tactile feedback module and a tactile feedback device. The haptic feedback electrode includes: an insulating layer; the conductive layer is laminated on the surface of the insulating layer; and the elastic layer comprises a plurality of granular elastomers, and the plurality of granular elastomers are distributed on the surface of the conductive layer. The tactile feedback electrode provided by the technical scheme has the technical effects that the plurality of granular elastomers are directly formed on the conductive layer to form the elastic layer, and the tactile feedback effect is achieved by utilizing the elastic deformation of the plurality of granular elastomers, so that the function of the elastic layer is not influenced. Meanwhile, the elastic layer comprises a plurality of granular elastomers, so that the occupied space of the elastic layer is reduced, the material consumption of the elastic layer is further reduced, the material utilization rate is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of tactile feedback, in particular to a tactile feedback electrode and a preparation method thereof, a tactile feedback module, and a tactile feedback device. Background technique [0002] With the development of science and technology, operators spend more and more time using electronic products, and the requirements for electronic products are also getting higher and higher. In order to improve the operator's tactile experience, tactile feedback modules are added to electronic products. The traditional tactile feedback module includes a plurality of tactile feedback electrodes. The tactile feedback electrode includes an insulating layer, a conductive layer arranged on the insulating layer, and an elastic layer arranged on the conductive layer. The elastic deformation of the elastic layer is used to play the role of tactile feedback. . However, traditional tactile feedback electrodes have the problems of l...
