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 flexible sensor device with multiple sensing functions, and a preparation method thereof. The flexible sensor device with multiple sensing functions comprises a surface package layer, an electrode layer and a multi-sensing function layer; the multi-sensing function layer comprises an electronic-electrode layer-ion gel layer-electronic-electrode layer; electric-conductingmetal copper wires are fixed at two ends of an upper electronic-electrode layer and a lower electronic-electrode layer in the multi-sensing function layer and led out; four metal electric-conducting copper wires are Top+, Top-, Bottom+, and Bottom-. By selecting different electrodes, the flexible sensor device can be worked on multiple sensing modes such as pressure, tensile and bending; furthermore, the invention provides a preparation method of the flexible sensor device with multiple sensing functions; the preparation process is simple, the cost is low, and the batch production is easy. Theflexible sensor device with multiple sensing functions can realize multi-mode sensing, and has the advantages of being high in sensitivity, fast in response and recovery and low in pressure detectionthreshold.

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...
