10/21/15 Stanford scientists have developed a pressure sensor that could be turned into artificial skin that would go over prosthetics, allowing people to feel objects as they touch them. The sensors send pulses to the brain that are interpreted as “touching”. It mimics our biological system.
The skin is made of plastic, imprinted with a waffle pattern so it compresses. Embedded inside the skin are tiny cylinders of pure carbon that conduct electricity. When the material is squeezed, the rods get closer together creating rapid pulses as the pressure increases. The end goal is to channel information from artificial sensors into the peripheral nerves that were once connected to the lost hand.
This advancement would not be possible without micro technology. Micro plays a crucial role in todays medical and pharmaceutical fields.
