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...
