Abstract

The invention discloses a pressure sensor with memory function, comprising: a first electrode, a second electrode, a functional layer located between the first electrode and the second electrode, the functional layer includes an insulating layer, and a metal filled in the insulating layer Nanoparticles and the phase change layer coated on the surface of the metal nanoparticles; the temperature change of the metal nanoparticles causes the phase change layer to change, and the number or size of the laser irradiation area is controlled to obtain a continuously changing equivalent resistance value; the pressure sensor is applied Pressure, the metal nanoparticles are in contact with each other, realizing the non-volatile continuous adjustment of the pressure sensor sensitivity. According to a pressure sensor with memory function, through the change of the temperature of the metal nanoparticles based on the plasma effect, the phase change layer is changed, thereby changing the resistance state of the phase change layer, and realizing the non-volatile and continuously adjustable sensitivity of the pressure sensor , the pressure sensor with memory function has low power consumption and low delay, and will be widely used in smart skins integrating sensing, storage and computing.

Description

technical field [0001] The invention relates to a pressure sensor, in particular to a pressure sensor with memory function. Background technique [0002] Pressure sensors are widely used in electronic skins. Existing pressure sensors do not have a memory function and do not have non-volatile and continuously adjustable sensing sensitivity, so they cannot be used to build smart electronic skins. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. Contents of the invention [0004] The purpose of the present invention is to provide a pressure sensor with a memory function, which has a memory-sensitive and non-volatile adjustable function, and can be used to build an intelligent electronic skin. [0005] To a...
