Description

technical field

[0001] The invention relates to the technical field of sensors, in particular to a displacement sensor based on electroactive elastomeric polymers. Background technique

[0002] With the development of soft robot technology, rigid drive and sensing technology in the traditional sense cannot meet the requirements. Soft robots widely use elastic or viscoelastic material elements, which have the ability of unlimited freedom of motion and continuous deformation, and can change their shape and size arbitrarily in a wide range. How to design flexible sensors to measure the displacement changes of soft actuators and robots is a hot spot and challenge in current research.

[0003] After searching the existing technical literature, it was found that the Chinese application number is 201410803826.1, and the name is "press-in dielectric elastomer pressure sensor", and the Chinese application number is 201510142816.2, and the name is "distributed flexible sensor based o...
