Abstract

The invention relates to a tensile pressure sensor based on printed transparent electrodes and a preparation method thereof. The tensile pressure sensor based on the printed transparent electrodes is characterized by comprising the components of an upper tensile substrate, a lower tensile substrate, printed transparent electrodes which adhere to the inner surfaces of the tensile substrates, and a dielectric layer which is sandwiched between the two printed transparent electrodes. Compared with the prior art, the tensile pressure sensor provided by the invention has advantages of high tensility, high transparency, relatively high sensitivity and relatively high stability. Furthermore, the tensile transparent electrode is prepared in a printing manner, and no complex micro nanometer machining process is required. The tensile pressure sensor has advantages of low cost, high efficiency and low energy consumption. The tensile pressure sensor is particularly suitable for large-area batch production and facilitates application and popularization of the sensor.

Description

technical field [0001] The invention belongs to the technical field of sensors, and relates to a stretchable pressure sensor and a preparation method thereof, in particular to a stretchable pressure sensor based on printed transparent electrodes and a preparation method thereof. Background technique [0002] Stretchable pressure sensor is a new type of sensor that has certain stretching deformation characteristics and can sense external pressure. Because it has both the stretchability of human skin and the skin's perception of external forces, it can simulate human skin to a certain extent and can be used in bionic "electronic skin" systems. Compared with traditional sensors, the new stretchable pressure sensor has the characteristics of stretchability, flexibility, biocompatibility, and high sensitivity. It is expected to be widely used in wearable electronics, human body sign monitoring, robot external force perception, and remote minimally invasive surgery. . [0003] A...
