Assessment of the Tongue-Drive System Using a Computer, a Smartphone, and a Powered-Wheelchair by People With Tetraplegia
Tongue-Drive System (TDS) is a wireless and wearable assistive technology that enables people with severe disabilities to control their computers, wheelchairs, and smartphones using voluntary tongue motion. To evaluate the efficacy of the TDS, several experiments were conducted, in which the performance of nine able-bodied (AB) participants using a mouse, a keypad, and the TDS, as well as a cohort of 11 participants with tetraplegia (TP) using the TDS, were observed and compared.
Stimulation Efficiency With Decaying Exponential Waveforms in a Wirelessly Powered Switched-Capacitor Discharge Stimulation System
The wireless switched-capacitor discharge stimulation (SCDS) system is capable of both transferring input energy to decaying exponential stimuli and delivering them to the neural tissue in a manner that consumes less energy than a conventional stimulator. Both computational model simulations and in vivo experiments verified the feasibility of using an SCDS system to efficiently activate neural elements in the brain.
