1, tissue engineering skin. Artificial skin has two biggest characteristics. First, rapid culture and amplification. Second, the clinical application is simple.
2. Artificial skin with liquid metal induction, comprising: a crosslinked polymer layer, a liquid metal circuit and a central processing unit. The artificial skin can transform the tactile sensation such as pressure and elasticity felt by the outside into the deformation of the cross-linked polymer layer. Because the liquid metal circuit clings to the cross-linked polymer layer, the resistance and capacitance of the circuit change, and then the central processor can convert the change of the electric signal of the circuit into a neural signal that can be recognized by the human body and transmit it to the nervous system, so that the skin feels different pressures and elasticity. The invention utilizes the flexibility of liquid metal to change the electrical properties of the liquid metal circuit through the deformation of the substrate, so that the liquid metal circuit has the function of a tactile sensor; Because of its sensitive tactile function, liquid metal circuit has the advantages of no individual difference, convenient storage and transportation, and can be widely used in skin transplantation and robot bionic skin.
