Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, the flexible sensor device with multi-sensing function is composed of 5 layers, including top packaging layer, top electronic electrode layer, ion gel layer, bottom electronic electrode layer and bottom packaging layer from top to bottom.

[0023] Among them, the structure of the top electron-electrode layer and the bottom electron-electrode layer is as follows figure 2 As shown, the material used is silica gel / AgNFs / MXene composite nanomaterial, in which there is a surface microstructure with convex and concave structures on one side of the silica gel film, and AgNFs / MXene is uniformly arranged on the side with convex and concave microstructures. As the pressure-sensing electron-electrode layer and the stretching, bending deformation-sensing layer.

[0024] The ion gel layer is made of a composite nanomaterial of PVA hydrogel and [...

Abstract

The invention discloses a multi-sensing function flexible sensor device and a preparation method thereof, wherein the multi-sensing function flexible sensor device includes a surface encapsulation layer, an electrode layer and a multi-sensing function layer, and the multi-sensing function layer includes an electron-electrode layer-ion gel Layer-Electron-Electrode Layer; A conductive metal copper wire is respectively fixed and drawn out at both ends of the upper and lower two Electronic-Electrode layers in the multi-sensing functional layer, a total of four metal conductive copper wires Top+, Top-, Bottom+, Bottom -. By selecting different electrodes, the present invention can work in multiple sensing modes such as pressure, stretching and bending. In addition, the present invention provides a method for preparing the multi-sensory functional flexible sensor device, which has a simple preparation process and low cost. Easy to mass produce. The multi-sensing function flexible sensor device of the present invention can realize multi-mode sensing, and has the advantages of high sensitivity, fast response and recovery, and low pressure detection threshold.

Description

technical field [0001] The invention relates to a sensor and its preparation, in particular to a flexible sensor device with multi-sensing functions and its preparation method. Background technique [0002] In the face of more and more special signals and special environments, new sensor technology has developed towards the following trends: developing new materials, new processes and developing new sensors; realizing the integration and intelligence of sensors; realizing the sensor technology hardware system and element Miniaturization of devices; cross-integrated sensors with other disciplines. [0003] At the same time, it is hoped that the sensor can also have the characteristics of transparency, flexibility, extension, freedom to bend or even fold, easy to carry, and wearable. With the development of flexible matrix materials, flexible sensors that meet the characteristics of the above trends have emerged on this basis. The flexible sensor made of flexible materials h...
