There are many things that robots are more equipped and safer to do than humans. Defusing bombs or delicate first aid procedures are a couple of examples where robots are more efficient tools. But there has been a roadblock where robots do not have the senses that humans do. Robots cannot smell, see, and hear like humans can. But now they can feel like humans can.
Rubber electronics and sensors that operate normally even when stretched to up to 50 percent of their length could work as artificial skin in robots, according to a new study. They could also give flexible sensing capabilities to a range of electronic devices, the researchers said. Like human skin, the material is able to sense strain, pressure and temperature, according to the researchers.
As the University of Washington explains:
"As the robot finger slides along a surface, serpentine channels embedded in the skin and filled with electrically conductive liquid metal stretch on one side of the finger and compress on the other. This changes the amount of electricity that can flow through the channels, which can be correlated with shear force and vibration."
