preparation example Construction

[0028] The present invention provides a method for preparing the electro-responsive smart hydrogel described in the above technical solution, comprising the following steps:

[0029] Polyethylene glycol diacrylate, acrylic acid, and photoinitiator were mixed and irradiated to obtain an electroresponsive smart hydrogel.

[0030] In the present invention, unless otherwise specified, the required preparation materials are commercially available products well known to those skilled in the art.

[0031] The invention mixes polyethylene glycol diacrylate, acrylic acid and photoinitiator. In the present invention, the photoinitiator is preferably phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide. In the present invention, the mass ratio of polyethylene glycol diacrylate, acrylic acid and photoinitiator is preferably 1:4˜16:0.01, more preferably 1:8˜12:0.01. In the present invention, the mixing process is preferably to first mix PEGDA and AA, then add a photoinitiator to the resultin...

Embodiment 1

[0046] Fabrication of electroresponsive smart hydrogel: Mix PEGDA and AA at a mass ratio of 1:16, then add photoinitiator (phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide, mass ratio of PEGDA 0.01:1), using a magnetic stirrer, the resulting solution was stirred in shading for 20 min to obtain a cross-linking solution;

[0047] Use Solidworks software to carry out 3D modeling of the PDMS inverted mold, and save the modeling file in STL. format; import the modeling file in STL. format into the 3D printer, and use ABS wire as the raw material to make an ABS resin inverted mold; On the ABS resin inverted mold, use the PDMS molding process to manufacture an inverted mold whose material is PDMS;

[0048] The cross-linking solution was injected into the inverted mold, and the inverted mold was placed under an ultraviolet lamp, and irradiated at 365 nm for 30 seconds; the PEGDA / AA electro-responsive smart hydrogel was obtained.

[0049] Support production: use Solidworks software to...

Embodiment 2

[0054] According to the scheme described in Example 1, the only difference is that the mass ratio of PEGDA and AA is 1:8.

Abstract

The invention belongs to the technical field of soft-bodied robots, and particularly relates to an electrically responsive intelligent hydrogel, a preparation method thereof, and a manipulator type soft-bodied robot. The electrically responsive intelligent hydrogel is a double-network cross-linked hydrogel formed by compounding polyethylene glycol diacrylate and acrylic acid; the hydrogel has theelectric response performance of bending towards an electric field cathode under the action of an electric field in an electrolyte solution; the hydrogel is applied in the manipulator type soft-bodiedrobot, and clamping and releasing of objects can be achieved through mutual cooperation and coordination of hydrogel fingers.

Description

technical field [0001] The invention relates to the technical field of soft robots, in particular to an electric response intelligent hydrogel, a preparation method thereof, and a hand-like soft robot. Background technique [0002] Smart hydrogel refers to a type of gel that can undergo reversible changes in volume or shape under external physical or chemical stimuli (such as light, temperature, magnetism, acid-base). Among them, the electro-responsive smart hydrogel has the characteristic of bending deformation in an electric field. Therefore, the electro-responsive smart hydrogel has been applied in the field of soft robots and is one of the commonly used materials for constructing soft robots. [0003] However, the existing electro-responsive hydrogels are limited to walking soft robots, and there is little research on the application of electro-responsive smart hydrogels to the field of manipulator soft robots in recent years. Contents of the invention [0004] The pu...
