Abstract

The invention discloses a flexible electrohydrodynamics driver. A drive unit comprises a flexible bag, a columnar electrode, dielectric fluid, a varnished wire, a hose and a plane flexible electrode.An inner cavity of the flexible bag is provided with the columnar electrode and fully filled with the dielectric fluid. The side portion of the flexible bag is in sealed connection with the hose, thevarnished wire is sleeved with the hose in a sealed manner, after penetrating through the hose, one end of the varnished wire stretches into the inner cavity of the flexible bag and is electrically connected with the end portion of the columnar electrode, and the other end of the varnished wire is connected with a high-voltage positive electrode. The outer surface of the flexible bag is coated with a layer of conductive flexible material to serve as the plane flexible electrode, or the flexible bag is arranged in water, and the water environment around the flexible bag serves as the plane flexible electrode. The flexible electrohydrodynamics driver is a novel drive based on the drive and deformation principle, the advantages of electrohydrodynamics flowing is brought into play, the main problems in the prior art are solved, and great application prospects are achieved in the field of soft body robots.

Description

technical field [0001] The invention belongs to a flexible driver in the field of soft robots and flexible materials, in particular to a flexible electrohydrodynamic driver. Background technique [0002] Compared with traditional rigid robots, soft robots made of flexible materials have great advantages in adapting to complex environments, performing autonomous tasks, and imitating the motion and function of biological systems, and in human-computer interaction devices, soft robots also have comparative advantages. Great application prospects. The core of soft robots is flexible actuators, and the existing flexible actuators are difficult to achieve a balance in terms of safety, reliability, controllability, durability, versatility, fast response, and muscle-like actuation characteristics. [0003] Existing flexible actuators are mainly divided into three categories. The first category is jet actuators, including flexible pneumatic actuators and flexible hydraulic actuator...
