Abstract

The invention discloses a tactile sensor based on a PVDF piezoelectric film, comprising a base, a lower conductive layer, a PVDF piezoelectric film, an upper conductive layer and a tactile contact layer, a lower conductive layer, a PVDF piezoelectric film, an upper conductive layer, and a tactile contact The layers are sequentially covered on the top of the substrate from bottom to top; the left and right sides of the lower conductive layer are provided with linear electrodes, and the front and rear ends of the upper conductive layer are provided with linear electrodes. The invention can cover a large area on the body surface of the robot, has unlimited structural size, and has high detection accuracy and high speed.

Description

technical field [0001] The invention belongs to the technical field of sensors, and more particularly relates to a tactile sensor based on pvdf piezoelectric film. Background technique [0002] Haptics is a necessary medium for robots to directly interact with the environment, which can ensure reliable physical and information interaction between robots and the external environment. The external information sensed by the tactile sensor can provide the necessary reference for human-computer interaction, and can also provide the relevant situation of 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 pvdf piezoelectric film is an urgent problem to be solved by those skilled in the art. SUMMARY OF THE INVENTION [0004] In view of this, the pre...
