The lab has also developed a wheelchair that a person can drive by using brain signals, rather than moving a joystick or pressing buttons.

Using videogame software code, he has built a virtual reality arm based on an arm wired with FES. Donoghue translates brain signals, and Kirsch uses them to drive the arm on a computer screen.

FORBES: Technology

As eardrum vibrations naturally create a usable voltage from brain signals, the prototype can build enough charge in a capacitor to drive a very low-power wireless transmitter that relays the electrochemical properties of the ear and potentially diagnoses balance or hearing problems.
