Problems solved by technology
[0003] In industry and experiments, when it is necessary to accurately characterize the flatness of the indenter or whether the surface is level, it is usually represented by pressure-sensitive paper. When the pressure acts on the pressure-sensitive paper, the pressure-sensitive paper will change color, and the judgment of whether the level is achieved by judging the color difference with human eyes , this method of subjectively judging whether it is level by color difference is not rigorous. For high-precision industries, slight deviations will lead to failure of experiments or production; in addition, pressure-sensitive paper is a one-time use product and is expensive. Press paper is not suitable for experimentation and production

application example 1
[0061] In this application example, the polymer hydrogel is N-isopropylacrylamide, and the temperature control device exists in the form of a temperature control membrane;
[0062] In this application example, N-isopropylacrylamide is used as the base material to coat the surface of the temperature control membrane;
[0063] When the temperature is raised to 50°C through the temperature control film, N-isopropylacrylamide is cured to a hardened state;
[0064] Spin-coat a layer of nano-silver on the surface of N-isopropylacrylamide, and prepare a touch layer by exposure and development;
[0065] A polyethylene terephthalate film is attached on the touch layer to protect the touch layer;
[0066] Establish communication with the integrated circuit (IC) on the touch layer through related technologies (for example, bonding (Bonding));
[0067] Record and calculate the data distribution generated by the capacitance formed by the touch layer through the integrated circuit;

A touch control device, a method for preparing the touch control device, and a method for performing pressure sensing by means of the touch control device. The touch control device comprises: a thermosensitive polymeric hydrogel layer, wherein the thermosensitive polymeric hydrogel layer has a first surface and a second surface, and the first surface is opposite the second surface; a first touch control layer and a second touch control layer, wherein the first touch control layer and the second touch control layer are respectively located on the first surface and the second surface of the thermosensitive polymeric hydrogel layer; and an integrated circuit having established a communication connection with the first touch control layer and the second touch control layer, wherein the integrated circuit is configured to record and calculate data distribution when a pressure acts on the touch control layers.
Description
technical field [0001] This article relates to but not limited to sensor technology, especially a touch device and a method for manufacturing the touch device. Background technique [0002] With the market demand for touch panels and the application of touch functions on mobile devices, various manufacturers have released flexible types such as Curved, Rollable, Bendable, and Foldable. (Flexible) panels and touch components. [0003] In industry and experiments, when it is necessary to accurately characterize the flatness of the indenter or whether the surface is level, it is usually represented by pressure-sensitive paper. When the pressure acts on the pressure-sensitive paper, the pressure-sensitive paper will change color, and the judgment of whether the level is achieved by judging the color difference with human eyes , this method of subjectively judging whether it is level by color difference is not rigorous. For high-precision industries, slight deviations will lead ...
