Researchers found that bone cells grow up to 80 percent faster on a rough surface compared to a smooth one.
Paper thin ‘e-skin’ developed.
An electronic skin created at UC Berkeley responds to touch by lighting up, with the light intensity getting brighter with harder touch. By using existing techniques currently used to create semiconductors, the team was able to fabricate the skin into a paper-thin piece of flexible polymer, integrating a transistor, organic LED, and a pressure sensor into each ‘pixel’, maintaining enough flexibility for the skin to be bent and flexed.
The skin could find uses ranging from a bandage that works as a health monitor which lights up to show blood pressure and pulse rates, to being used to give robots a finer sense of touch.
The team now hopes to make similar skins which respond to not only touch, but also light and pressure.
