Researchers craft smiling robot face from living human skin cells
Human cells isolated from juvenile foreskin are flexible enough to grin when moved.
As a proof of concept, the team engineered a small robotic face capable of smiling, covered entirely with a layer of pink living tissue. The researchers note that using living skin tissue as a robot covering has benefits, as it's flexible enough to convey emotions and can potentially repair itself. They then applied a mixture of human skin cells in a collagen scaffold, allowing the living tissue to grow into the anchors.
