Brain cells can be activated by a prosthetic hand.

Researchers from Stanford University have improved artificial hands by attaching some flexible sensors on the fingertips, which can generate some electrical signals that can communicate with our brain directly instead of via a processor or a computer to translate back the signals to our brain. Engineers have built a flexible sensor that detects touch and, just like skin, produces electrical pulses that get faster when the pressure increases. They have also used those pulses to drive neuronal ...
