Abstract
A device for vestibular substitution includes a mouthpiece fitting entirely within a person's mouth in a shape that conforms to the palate. The mouthpiece encases a circuit board containing an electronic system that can deliver electrical pulses to electrical stimulators touching the palate based on head movement. The electronic system includes a motion sensor, a control unit; a stimulation circuit; and a battery. The control unit is preferably a microcontroller with a digital Input/Output capability, a Serial Peripheral Interface/Inter-Integrated Circuit protocol, a timer, and an oscillator for sensor interfacing and timing control. The microcontroller enables processing data from the accelerometer to indicate head movement, and controlling each embedded electrical stimulator to deliver electrical pulses with adjustable waveform parameters. The device may also include a wireless transceiver for remote control of the device from outside the person's mouth.
