¡°In this study, we managed to replicate human to some extent by a face with the same and as humans,¡± Shoji Takeuchi, the team leader, said in a news release. In the process, he added, ¡°we identified new challenges, such as the necessity for surface wrinkles and a thicker epidermis to a more humanlike appearance.¡±

The promises to make robots more lifelike ¡ª and in the future, the researchers say, techniques could also be used on humans, in the cosmetics and surgery industries. Their findings were published in the journal Cell Reports Science.

To overlay and the lab-produced skin on a robotic skeleton, a layer of collagen gel containing cultured human dermal fibroblasts (a type of connective tissue cell) binds to an innovative of tiny V-shaped perforations in the surface, letting the skin move with the underlying structure without tearing or peeling. The work of muscles ¡ª creating a smile, and other motions ¡ª is done by actuators.
