Abstract

The invention discloses a device and a method for testing sensitivity of flexible film sensing elements. The device for testing the sensitivity of the flexible film sensing elements comprises a pair of translation assemblies which are arranged on a bottom plate, an aluminum sheet which is clamped between the pair of translation assemblies and a multimeter; the pair of translation assemblies draw close to each other to bend the aluminum sheet; the aluminum sheet is used for adhering a flexible film sensing element; and the multimeter is connected with the flexible film sensing element and is used for measuring a resistance value of the flexible film sensing element. Because the aluminum sheet is compressed by utilizing the pair of translation assemblies, the flexible film sensing element arranged on the aluminum sheet is subsequently bent, and the sensitivity of the flexible film sensing element is calculated through detecting the change of a resistance value of the flexible film sensing element during bending. The sensitivity testing device disclosed by the invention has the advantages of being simple in structure, low in measuring requirements, convenient in measurement and low incost.

Description

technical field [0001] The invention relates to the technical field of sensitivity measurement, in particular to a sensitivity testing device and method for a flexible thin film sensing element. Background technique [0002] Most of the flexible strain sensing elements are composed of conductive layers on some flexible polymer substrates. By sensing external stress and strain, the resistance of the conductive layers on the polymer substrates is changed. In the prior art, the sensitivity coefficient characterization method of the traditional flexible strain sensing element requires high equipment requirements and is expensive, which is not conducive to universal use. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a flexible thin film sensing element sensitivity testing device and its method in view of the above-mentioned defects of the p...
