Smart artificial skin detects hot and cold
A smart artificial skin that detects hot and cold. A noticeable goal reached by two medical teams, Korean and American, and coordinated by theSeoul National University. Compared to previous tests, this one has led to the creation of smart prosthetic skin instrumented with ultrathin, single crystalline silicon nanoribbon strain, pressure and temperature sensor arrays as well as associated humidity sensors, electroresistive heaters and stretchable multi-electrode arrays for nerve stimulation. Tested on rats, the skin has proved that animals’ brain reacted to stimuli sent by sensors. A big step forward in aid of people undergoing surgery that replaces hands and feet. Results are available on Nature Communications.
