Problems solved by technology

[0005] In the above-mentioned patent, although the axial directions of a plurality of one-dimensional conductive materials are basically oriented in the same direction, so that they have directional expansion characteristics, however, the one-dimensional conductive materials are arranged in parallel or stacked at intervals. After the breakdown point is generated, a short circuit will be caused here, which will affect the stretching performance of the electrostrictive material, and its conversion rate of electrical energy conversion to mechanical energy is low, which consumes a lot of energy and increases the cost of use.

Description

technical field [0001] In particular, the invention relates to a process for preparing hollow fibers based on electrostrictive materials. Background technique [0002] Electrostrictive material is a material that deforms under the action of electric field, voltage or current to generate stretching motion, thereby realizing the conversion of electrical energy to mechanical energy. Electrostrictive materials are also known as artificial muscle materials due to their muscle-like motion. Artificial muscle fibers will be widely used in future super robots, artificial organs, aerospace and deep-sea automatic manipulation systems. It has become the subject of high-tech research in the world today. [0003] Traditional electrostrictive materials include shape memory alloys, piezoelectric ceramics, ferroelectric polymers, etc. However, these electrostrictive materials have low electrostriction and poor flexibility. Furthermore, there is a dielectric elastomer material in the pr...
