Flexible pressure sensor and flexible pressure sensing array

Abstract

The invention provides a flexible pressure sensor and a flexible pressure sensing array. The flexible pressure sensor comprises a substrate layer made of a flexible high-molecular polymer material, aelectrode layer, and a sensing layer. The electrode layer is arranged on the surface of the substrate layer, the flexible high-molecular polymer is adopted as a matrix of the electrode layer, and theflexible high-molecular polymer is filled with micron-sized silver sheets or other micro-nano conductive materials; and the sensing layer is electrically connected with the electrode layer, the matrixof the sensing layer adopts the flexible high-molecular polymer, and the flexible high-molecular polymer is filled with nano carbon black particles or other micro-nano conductive materials. Accordingto the invention, the geometrical shape of the electrode layer and the microstructure of the sensing layer are designed in a stretchable mode, so that the flexibility and ductility of the pressure sensor and the integration performance of the pressure sensor and the non-structural surface are effectively improved; and the structure is simple, machining is convenient, wire leading is easy, and cost is low.

Description

technical field [0001] The invention relates to the technical field of pressure sensors, in particular to flexible pressure sensors and flexible pressure sensing arrays, and their applications in flexible wearable devices and robotic haptic devices. Background technique [0002] Whether it is robots widely used in industrial manufacturing and service industries, or increasingly popular wearable electronic devices, or clinical medicine, flexible sensors are indispensable components. In recent years, with the deepening and expansion of flexible sensor research worldwide, a large number of flexible sensor structure designs have been proposed. However, many devices are difficult to meet the requirements of the above applications due to the lack of excellent bendability and stretchability of their structures. Therefore, on the premise of ensuring the performance of the sensor, how to improve its flexibility and elasticity has become a key technical problem to be solved urgently ...
