Abstract

The invention discloses an electro-deformable film array, its preparation method and application. The thin film array includes an electrode film, a core layer film, an electrode array and an electrical connection layer, and the electrical connection layer includes an electrical connection circuit and an electrical barrier layer; a number of electrical contacts, one end of which passes through the electrical barrier layer, and is connected to the electrical connection circuit. The selected point is in electrical contact; the electrode film, the core film, the electrode array and the electrical connection layer are stacked in sequence, and the other end of the electrical contact is in electrical contact with the set point on the electrode array. The preparation method includes: processing and forming the aforementioned structural layers respectively, and then combining them with heat and pressure to obtain the target product. By adopting the above-mentioned design, each component can be prevented from interacting with each other during processing, and the unit quantity scale of the electro-deformable thin film array can be greatly increased. The invention can be used in the fields of braille display, graphic anti-counterfeiting and key, deformation mirror, three-dimensional graphic display, man-machine interface, pressure imaging and the like, and has wide application value.

Description

technical field [0001] The invention specifically relates to an electro-deformable film array, its preparation method and application, and belongs to the field of material science. Background technique [0002] Electrodeformable film material is an ion-type electrically actuated deformation material, which has outstanding advantages such as light weight, good flexibility, low driving voltage, rapid response and large deformation. It can be used to make deformation devices and mechanical sensing devices. It is a new type of intelligent material that has emerged in the past two decades and has great application potential. [0003] Electrodeformable film materials are usually used as a whole in strips or blocks. For example, Japan’s EAMEX company has developed a robotic fish product that uses the bending deformation of strip materials to push fish to swim; The repeated vibration deformation of thin film strip materials simulates the flying action of birds; M. Shahinpoor of the...

Problems solved by technology

[0006] However, there are very few technological methods related to lead wires. In the existing research, one method is to directly connect wires to each deformation unit. Because the wires have a certain quality and binding force, not only the deformation of the unit is greatly affected, but also the stability of the electrical connection. It cannot be well guaranteed; another method is to design a special-shaped unit structure, and extend the electrodes of the deformation unit to the edge of the film to apply voltage. In this method, the electrode leads will occupy a certain film area, which is not conducive to large-scale array design
