preparation example Construction

[0057] See figure 1 . An embodiment of the present application provides a method for preparing a pressure sensor 10, including the following steps:

[0058] S110, providing an elastic film 100 and a reduced graphene oxide film 200;

[0059] S120, stretch the elastic film 100 along the first direction and the second direction, so that the elastic film 100 is elongated in the first direction and the second direction;

[0060] S130, transferring the reduced graphene oxide film 200 to the elastic film 100 stretched in the first direction and the second direction; and

[0061] S140, releasing the elastic film 100 stretched in the first direction and the second direction, so that the stretched elastic film 100 shrinks, so that the reduced graphene oxide film 200 produces a wrinkled structure.

[0062]The elastic film 100 can be stretched and retracted to return to its original shape. One side of the elastic film 100 can fix the reduced graphene oxide film 200 . In one embodimen...

Abstract

The invention provides a pressure sensor preparation method including S110, providing an elastic thin film and a reduced graphene oxide thin film; S120, stretching the elastic thin film in a first direction and a second direction, so that the elastic thin film stretches in the first direction and the second direction; S130, transferring the reduced graphene oxide thin film to the stretched elasticthin film in the first direction and the second direction; S140, releasing the stretched elastic thin film in the first direction and the second direction, so that the stretched elastic thin film iscontracted to enable the reduced graphene oxide thin film to generate a wrinkle structure.

Description

technical field [0001] The present application relates to the field of sensors, in particular to a method for preparing a pressure sensor and the prepared pressure sensor. Background technique [0002] A pressure sensor is a device that converts pressure into a measurable electrical signal. Pressure sensors are widely used, from scientific detection applications such as wind force measurement to industrial requirements such as automation systems, from precision measurement of micro force such as precision balances to general object weight measurement such as ordinary electronic balances, they play an indispensable role in various fields. For different fields, the precision requirements and range ranges of the pressure to be measured are often different, especially in the fields of biological detection and medical detection, extremely sensitive sensors are required, while traditional pressure sensors have low sensitivity. Contents of the invention [0003] Based on this, i...
