At a leading Japanese university, the development of lifelike, self-healing ‘skin’ for robots is a hot topic being researched. The primary aim of this technology is to create humanoid robots with realistic appearances and improved sensory reception.
As pioneers in this field, a close study of human skin and its exceptional self-restoration capabilities is being done. The objective is to replicate these properties in robots, enabling them to swiftly and independently recover from damage and wear. Furthermore, the development of algorithms and sensors mimicking the human tactile sensory system are also in progress.
The idea of creating better adhesion between the skin’s subcutaneous layer and the robot’s features comes from prior studies conducted with finger-shaped robots wearing engineered skin.

The potential for this enhanced adhesion could lead to more efficient transmission of sensory information, increasing the robots’ functionality and responsiveness.
The use of a unique ‘plasma treatment’ technique that involves tiny, v-shaped perforations in the facial plate is a breakthrough in the field. This method, in conjunction with a collagen gel, has improved the stability of the attachment and minimized potential damage to the skin and underlying structures.
To test the effectiveness of this innovative approach, ‘living skin’ has been attached to a flat surface with moving parts and a 3D humanoid robot face. Interestingly, the new visage demonstrated the ability to express emotions like ‘smiling,’ without peeling or tearing of the skin.
Plans are already being made to improve the synthetic skin’s range of emotions. The researchers believe future versions could even include human-like features such as pores, glands, fat, and potentially even nerves.
However, despite the exciting prospects of this research, the researchers acknowledge the need for more advancements. They also emphasize the importance of addressing ethical considerations and setting regulations for the use of such technology before widespread adoption.
While humanoid robots might replace human workers in hazardous environments or perform complex surgeries in the future, a cautious approach is needed due to the potential societal implications of such advancements.
