Abstract

The invention discloses a flexible pressure sensor and a preparation method thereof. The flexible pressure sensor comprises an upper conductive electrode layer, a pressure sensitive dielectric layer and a lower conductive electrode layer stacked in order from the top to bottom. The structure is simple. The pressure sensitive dielectric layer can be deformed under external pressure, therefore, an obvious change of an electrical signal is caused, after the external pressure is removed, the deformation is restored, the original state is restored, and the sensitivity to the electrical signal is high.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a flexible pressure sensor and a preparation method thereof. Background technique [0002] Flexible pressure sensor is a kind of flexible electronic device used to sense the force on the surface of certain objects. It can be attached to the surface of various irregular objects. It has broad application prospects in the fields of medical health, robotics, biomechanics, etc. people's attention.
