Flexible low-voltage voltage-dependent resistor and production method thereof

Abstract

The invention relates to a flexible low-voltage voltage-dependent resistor and a production method thereof. The conventional voltage-dependent resistor is large and cannot be bent, and thereby cannot be applied in flexible devices. The flexible low-voltage voltage-dependent resistor is of a layered structure, and sequentially comprises a flexible substrate, a lower electrode film, a ZnO film and an upper electrode film, the surfaces of the upper and the lower electrode films are respectively connected with an upper electrode lead and a lower electrode lead, the flexible substrate is a PET (polyester) film, and the upper and the lower electrode films are Pt films. The specific production method includes the following steps: a layer of Pt film is deposited on the surface of one side of the flexible substrate to serve as the lower electrode film; by means of the masking technology, part of the lower electrode film is covered, a layer of ZnO film is deposited on the exposed part of the lower electrode film, and the lower electrode lead is bonded; a layer of Pt film is deposited on the ZnO film to serve as the upper electrode film, and the upper electrode lead is bonded. The process ofthe method is simple, and the produced flexible low-voltage voltage-dependent resistor has unique flexibility and extensibility, and can be bent.

Description

technical field [0001] The invention belongs to the field of electronic technology, and relates to a flexible and bendable low-voltage varistor and a preparation method of the low-voltage varistor. Background technique [0002] With the development of portable and flat electronic devices, more and more scientific and technical personnel pay more and more attention to bendable and foldable electronic devices. Flexible electronic devices have become a research and development hotspot in recent years. Flexible electronic devices such as flexible displays, flexible triodes and even flexible mobile phones have been reported. Numerous instruments and equipment such as cardiac pacemakers, medical equipment, video cameras, hearing aids, printers, scanners, etc. require flexible and bendable electronic protection components. .

However, no one has proposed flexible and bendable electronic protection components so far

As a protective element, varistors have been widely used in various protective circuits. However, ordinary varistors are bulky and inflexible, and cannot be used in flexible and bendable devices.
