b. Plastic skin
c. Rubber limbs
d. Rubber skin
ANSWER: Plastic skin
Following a decade of studying, researchers from Stanford University have attained a major breakthrough to mimic the skin’s ability for sensing touch, pressure, temperature and pain. They have invented a revolutionary plastic skin comprising two layers namely a sensing mechanism on the top and a bottom layer transmitting electric signals onto the biochemical stimuli for nerve cells to get. The skin is able to detect pressure over the same range as human skin. This is the first time a synthetic skin has been developed capable of detecting pressure and transmitting signals to the nervous system. There are thick grapheme tubes which allow the plastic skin to resemble human skin and transmit pressure information through short pulses of electricity akin to a Morse Code to the brain.
