Tactile sensor based on pvdf piezoelectric film

Abstract

The invention discloses a tactile sensor based on a pvdf piezoelectric film. The tactile sensor comprises a substrate, a lower conducting layer, the pvdf piezoelectric film, an upper conducting layerand a tactile contact layer, and the lower conducting layer, the pvdf piezoelectric film, the upper conducting layer and the tactile contact layer sequentially cover the top end of the substrate frombottom to top; the left and right sides of the lower conducting layer are provided with linear electrodes, and the front and rear ends of the upper conducting layer are provided with linear electrodes. The sensor can cover the body surface of the robot in a large area, the structural size is not limited, the detection precision is high, and the speed is high.

Description

technical field [0001] The invention belongs to the technical field of sensors, and more specifically relates to a touch sensor based on PVDF piezoelectric film. Background technique [0002] The sense of touch is a necessary medium for the robot to achieve direct interaction with the environment, which can ensure reliable physical and information interaction between the robot and the external environment. The external information sensed by the tactile sensor can provide the necessary reference for human-computer interaction, and also provide the relevant information of the collision for the safety control strategy of the robot. Traditional tactile sensors are made of hard materials such as silicon and metal, which lack flexibility and are not easy to attach to curved surfaces for measurement. [0003] Therefore, how to provide a tactile sensor based on a PVDF piezoelectric film is an urgent problem to be solved by those skilled in the art. Contents of the invention [0...
