Abstract

The invention provides a flexible pressure sensor, and the pressure sensor comprises two flexible conductive composite films, wherein the flexible conductive composite films are stacked together, and one surface, facing the other flexible conductive composite film, of one flexible conductive composite film face is provided with a single-layer miniature hemisphere array which is arranged in a periodic manner.

Description

technical field [0001] The invention belongs to the field of wearable flexible electronics, and in particular relates to a flexible pressure sensor and a preparation method thereof. Background technique [0002] The flexible pressure sensor is a flexible electronic device used to sense the force on the surface of some objects. It can be attached to the surface of various irregular objects. It has broad application prospects in the fields of medical health, robotics, and biomechanics. people's attention. With the development of science and technology, whether flexible pressure sensors can combine flexibility and accurately measure pressure distribution information has become the focus of people's attention. Since the micro-nano structure of the sensor can not only improve the response speed of the sensor, but also recover the elastic deformation of the sensor faster, the pressure sensor with a micro-nano structure has become the focus of attention in academia and industry. ...
