Abstract
A novel system to control robotic/prosthetic limbs with a tongue-based scheme is presented in this paper. In the proposed system six off-the-self pressure sensors soldered on a flexible PCB and placed in the inner part of cuspides, central and lateral incisors of the lower arch, are interfaced with electronics and wireless transmitters to form the complete system. The control system sends the appropriate commands to the prosthesis when users apply force to one of the pressure sensors with their tongue. Each pressure sensor represents one gesture for the prosthesis. The touch with the tongue results in an increase of the read pressure by the sensor. If the pressure exceeds a predetermined threshold the prosthesis is activated via wireless transmission of data. To package the system in the mouth a protective encapsulation was made using PDMS. Different thicknesses and concentrations of PDMS were tested to determine the optimum trade-off between the minimum exerted force by the user that activates the prosthesis and the threshold below which the prosthesis is not active.
