Embodiment Construction

[0044] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0045] Such as figure 1 This embodiment is a schematic structural diagram of the muscle drive module based on temperature-responsive smart hydrogel (ie, temperature-responsive hydrogel), including temperature-responsive smart hydrogel interlayer 1 (ie, based on temperature-responsive hydrogel) The driving layer), the stretchable electric heating layer 2 attached to the temperature-responsive smart hydrogel interlayer, and the upper and lower layers of the flexible protective layer 3 in which the temperature-responsive smart hydrogel is wrapped.

[0046] The temperature-responsive hydrogel used to prepare the driving layer in this embodiment is as follows:

[0047] It includes a cross-linked first network monomer and a second network monomer, the network structure formed by the first network monomer is a flexible network and has temperature response characteristics...

Abstract

The invention discloses a muscle driving module based on temperature responsiveness hydrogel; the muscle driving module comprises a driving layer based on the temperature responsiveness hydrogel, a flexible protection layer wrapping the driving layer, and an electrothermal layer arranged between the driving layer and the flexible protection layer. The muscle driving module uses flexible material to serve as a muscle auxiliary device, thus preventing machinery damage on human body; an electrothermal driving mode can drive the material to deform, and is easily controlled, thus obtaining different driving forms.

Description

Technical field [0001] The invention relates to the technical field of hydrogels, in particular to a muscle driving module based on temperature-responsive hydrogels. Background technique [0002] Hydrogel material is a soft material formed by filling water molecules in a polymer network structure. Because of its wet and soft properties, it is widely used in bioengineering, drug delivery, tissue engineering and other fields. Smart hydrogel material is a type of hydrogel, which is very sensitive to changes in the external environment. If the external temperature, pH, photoelectric signal, special chemical molecules and other factors change slightly, the smart hydrogel itself can respond accordingly. Changes in physical structure or chemical structure. Therefore, because smart hydrogels can quickly indicate changes in some external environmental factors, under certain external stimuli, change their volume or make other qualitative responses, some smart hydrogels with good mechanic...
