Problems solved by technology

However, due to the high hardness of the ceramic filler, the dielectric constant of the obtained composite material increases with the increase in the amount of the filler, and the modulus also increases significantly, so that it needs to be deformed at a very high voltage and a large amount of barium chinate The compatibility with the silicone rubber matrix is ​​poor, it is difficult to disperse evenly, and it is easy to cause the local electric field to be too high and the breakdown voltage of the material to drop

Abstract

The invention discloses an electronic artificial muscle electric actuator and a preparation method and application thereof in a finger driving device. The electronic artificial muscle electric actuator is composed of a modified graphene oxide / silicone rubber basement membrane, graphite / silicone rubber electrodes fixed on two sides of the basement membrane, a wire and a high-voltage pulse electricsignal, wherein the basement membrane is prepared by doping IPDI modified graphene oxide in silicone rubber, and the graphite / silicone rubber electrode is prepared by doping graphite in silicone rubber and is fixed on two sides of the basement membrane. The dielectric constant is improved by adding the modified graphene oxide into the basement membrane, so that the actuating performance is improved. The electronic artificial muscle electric actuator can generate larger deformation under the same electric field voltage, can be used for a tactile sensor, can change the magnitude and the frequency of driving force on fingers by adjusting the voltage and the frequency in the aspect of finger driving, and is suitable for different crowds.
