Device and method for preparing electrode

Abstract

The invention discloses a device and a method for preparing an electrode. The device for preparing the electrode comprises a roll-to-roll device used for stretching a stretchable substrate and a spreading device used for spreading conductive ink on the substrate after being stretched so as to form an electrode layer. The device for preparing the electrode uses the roll-to-roll device for stretching the stretchable substrate, and then applies roll-to-roll technology into production equipment of the stretchable electrode, achieves online production of the stretchable electrode, uses simple, convenient and efficient characteristics of the roll-to-roll technology, reduces manufacture cost of the stretchable electrode, and achieves mass production of the stretchable electrode.

Description

technical field [0001] The invention relates to the technical field of stretchable electrode preparation, in particular to a device and method for preparing electrodes. Background technique [0002] With the gradual advancement of unmanned vehicles, wearable devices, the Internet of Things, human-computer interaction, and interconnected electronics, easy-to-wear and biocompatible electrical devices have gradually entered people's field of vision. This will require a large number of better adaptable electronic devices. In order to adapt to various environments and various surfaces, the importance of stretchable devices will become increasingly prominent. To achieve stretchable devices, stretchable electrodes are required. [0003] According to the work achieved by domestic and foreign researchers in the field of stretchable electronics, the following information can be drawn: At the laboratory level, research on stretchable electronics has made great progress in recent years...

AI Technical Summary

Problems solved by technology

However, at present, the main research on stretchable electronics is still concentrated in the laboratory, which is affected by the complexity of the manufacturing process (requires a combination of multiple steps such as photolithography, transfer, bonding, alignment, packaging, etc.), the stability of heavy-duty stretching , poor electrical conductivity and other factors

Therefore, at present, there are relatively few studies on mass production of stretchable electrodes, and it is difficult to achieve mass production of stretchable electrodes.
