When the scientists tried the same experiment with the water-repellent humanlike skin, the robotic finger could flick the foam beads away without them sticking, the authors said. These beads are commonly used as filler material in products such as beanbags and some stuffed animals. When researchers used a robot with wet surface material, polystyrene foam beads stuck to it, according to the study.

The skin could also repel water, which expanded what tasks the robot could perform. His team put a collagen bandage on a part of the finger that had been inflicted with a wound to mend it, and the robot was able to move freely after the protein repaired the skin.Ĭollagen is a major component of human skin and has healing properties, according to a 2021 study. In the trials, the elastic human skin moved freely while the finger made different motions, Takeuchi said. A keratinocyte is the main type of cell that makes up the human epidermis, the outermost layer of skin, he said. Dermal fibroblasts are the primary cell type in the connective tissue of the skin.Īfter the solution conformed around the finger, Takeuchi applied human epidermal keratinocytes to the outside.
The robotic finger was first submerged in a solution of collagen, which is a fibrous protein, and human dermal fibroblasts, the two major components that make up human skin. Courtesy Wake Forest Institute for Regenerative MedicineĮvery day, 17 people die waiting for a donor organ.
