Researchers Turn up with E-Skin to Provide Sense of Touch to Robots
The first ever user-friendly sensor network has now been created on flexible plastic by a researcher at UC Berkeley's Lawrence Berkeley National Laboratory. Ali Javey, the researcher, said they were not concentrating only on manufacture of devices, but at building systems as well.
The professor of electrical engineering and computer sciences said the new e-skin or electronic skin has been built on his earlier work. Semiconductor nanowire transistors coated on thin rubber sheets' top were used for the same.
It has been found that e-skin has the potential to respond to touch by illuminating right away. The brightness of the light emitted by it depends on the pressure imposed on the same.
The latest study has appeared in the online journal Nature Materials on Sunday, July 21. It is being said that the technology would likely help in creation of things such as wallpapers, which double as touchscreen displays, or dashboard laminates. The latter helps drivers in adjusting electronic controls with a hand wave.
Besides, it is being hoped that future robots could be provided by the new technology with a sense of touch. As per the findings, the e-skin's experimental samples measure 16-by-16 pixels, within each of which is a transistor, a pressure sensor and an organic LED.
According to Javey, "With the interactive e-skin, we have demonstrated an elegant system on plastic that can be wrapped around different objects to enable a new form of human-machine interfacing".
