Problems solved by technology

[0003] In actual use, if the helmet has been dropped heavily, or if the material has become brittle due to its long service life, there may be cracks invisible to the naked eye on the shell or the hat lining. At this time, the helmet no longer has rigidity. The safety guarantee performance when leaving the factory, if you continue to use it, there will be safety risks

Abstract

The invention discloses a circuit and film for deformation detection, which are arranged on the surface to be tested. The circuit includes a plurality of pixel units, including (n / 2) rows*m columns, and each pixel unit has a first input terminal, The second input terminal and the output terminal, the first input terminal is used to receive the first voltage signal, the second input terminal is used to receive the pulse signal, the output terminal is used to output the current signal, when the current signal changes, then It is determined that the area of ​​the corresponding pixel unit changes, and the surface to be measured is deformed. For the circuit and film of the present invention, when the output current signal changes, it means that the area of ​​the corresponding pixel unit has changed, and since the circuit and the film are attached to the surface to be tested, it means that the surface to be tested has been deformed. Therefore, it is convenient for users to detect and replace abnormal products in time, and accidents are avoided. Moreover, the detection method of the present invention is intuitive and easy to operate.

Description

technical field [0001] The invention relates to a circuit and a film used for deformation detection, in particular to a circuit and a film which can sensitively detect the deformation of an object to be measured. Background technique [0002] Safety helmets are protective equipment to prevent impact objects from hurting the head. Consists of shell, lining, lower chin strap and rear hoop. The cap shell is hemispherical, firm, smooth and elastic, and the impact and puncture kinetic energy of the striking object is mainly borne by the cap shell. There is a certain space between the cap shell and the cap liner, which can buffer and disperse the instantaneous impact force, so as to avoid or reduce the direct injury to the head. Impact absorption performance, puncture resistance performance, lateral rigidity, electrical insulation and flame retardancy are the basic technical performance requirements for safety helmets. [0003] In actual use, if the helmet has been dropped heav...
