The invention discloses a resistance-capacitance hybrid pressure sensor and a method for using the same. It comprises a piezoresistive material layer, a conductive electrode layer and a substrate layer. The piezoresistive material layer is composed of a material whose resistance is sensitive to pressure. The upper and lower layers are respectively located on the upper and lower surfaces of the piezoresistive material layer, and there is a substrate layer on the upper and lower surfaces of the conductive electrode layer. The pressure sensor is made into an array and used in electronic devices such as touch screens. By measuring capacitance and resistance in different application environments, it can not only have the advantages of high sensitivity, strong durability, and mature technology of capacitive touch screens, but also have resistance The type touch screen can detect pressure, strong water resistance and so on. The two functions of the invention share the same sensor structure, the structure and principle are simple, and the existing capacitive touch screen technology and equipment can be used, the cost is low, and it is suitable for large-scale promotion. |
