flexible pressure switch

Abstract

The invention discloses a flexible pressure switch. A flexible electrode area and a flexible non-electrode area are formed on a flexible circuit board at the bottom layer. Two flexible electrodes separated from each other are arranged in the flexible electrode area. The adhesive layer is positioned and bonded with a conductive elastic composite body, and a pressure contact cavity area facing the flexible electrode area is formed on the conductive elastic composite body, and the upper surface of the inner wall can contact two flexible electrodes simultaneously or successively when pressed to make the circuit conduction. The opening and closing resistance threshold range of the switch is adjusted by changing the resistivity of the conductive layer or the flexible electrode; the opening and closing of the switch is controlled by adjusting the conduction pressure range of the switch through structural design and changing the hardness of the conductive elastic composite. The switch has simple preparation process, low cost, stable performance, is suitable for mass production, and can meet the functionality and wearing comfort of the product at the same time. It is suitable for wearable smart devices such as smart insoles, smart shoes, smart seats, and smart mattresses. in the device.

Description

technical field [0001] The invention relates to a switch device, in particular to a flexible pressure switch, which belongs to the technical field of smart wearable electronic equipment components. Background technique [0002] Traditional pressure sensing components have large volume and high stiffness, which limits their use on any two flexible or flexible / rigid contact surfaces, and this limitation is more manifested in the field of flexible smart wearables. It is prominent that traditional pressure sensor components cannot meet the functionality and wearing comfort of smart wearable products at the same time. In order to overcome the above limitations and obtain the pressure distribution directly or indirectly related to the surface of the human body, it is necessary to develop a flexible pressure switch, which needs to meet the functionality of the product and the comfort of wearing at the same time, and has a simple manufacturing process. , low cost, stable performanc...
