Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0032] figure 1 is a cross-sectional view of a flexible pressure film sensor.

[0033] figure 2 is an exploded view of the flexible pressure film sensor.

[0034] Such as figure 1 and figure 2 As shown, the flexible pressure film sensor includes: a first insulating protective layer 101 , a conductive electrode layer 102 , a supporting adhesive layer 103 , a sensitive ink layer 104 and a second insulating protective layer 105 .

[0035] The material of the first insulating protection layer 101 includes but not limited to PET film, PVC film, PE film, and the preferred thickness is 10um-300um. The material of the second insulation protection layer 105 includes but not limited to PET film, PVC film, PE film, and the preferred thickness is 10um-300um. The shape of the first insulating protection layer 101 and the second insulating protection...

Abstract

The invention provides a sensitive printing ink material, a flexible pressure film sensor and a preparation method of the flexible pressure film sensor. The flexible pressure film sensor comprises a first insulating protective layer, a conductive electrode layer, a supporting adhering layer, a sensitive printing ink layer and a second insulating protective layer; the conductive electrode layer andthe sensitive printing ink layer are arranged between the first insulating protective layer and the second insulating protective layer; the sensitive printing ink layer is composed of conductive sensitive printing ink materials with concave-convex surface micro structures; the supporting adhering layer is located between the first insulating protective layer and the second insulating protective layer, and bonds the first insulating protective layer and the second insulating protective layer. The flexible pressure film sensor has the advantages that a force-resistance change curve relation isimproved, the intensity of external stimulating force can be recognized to a certain degree, and the flexible pressure film sensor is well applied to the fields of human body pressure distribution detection, an automatic safety seat system and man-machine touch control.

Description

technical field [0001] The invention relates to a sensitive ink material, a flexible pressure film sensor and a preparation method thereof. Background technique [0002] At present, the main performance characteristics of the flexible membrane switches sold on the market are externally stimulated, that is, when subjected to a very weak external force, the resistance will decrease sharply, and after signal collection and processing, only the presence or absence of external force can be judged. exists, but it is impossible to identify the magnitude of the external force. Contents of the invention [0003] The object of the present invention is to provide a sensitive ink material, a flexible pressure film sensor and a preparation method thereof; to fundamentally solve the above-mentioned technical problems and overcome the above-mentioned defects in the prior art. [0004] The invention provides a flexible pressure film sensor, comprising a first insulating protective layer,...
