Live Demonstration: Low Power System for Event-Driven Control of Functional Electrical Stimulation

The demonstration presents a surface ElectroMyoGraphy (sEMG) low power wireless system used to control Functional Electrical Stimulation for rehabilitative neuro-muscular applications. An event-driven technique is applied to the bio-signal, minimising power consumption, complexity, and transmitted data. The acquisition board transmits four channels sEMG event data, through a Bluetooth Low Energy wireless module, to a workstation where they are processed in order to control the stimulation pattern of a commercially available functional stimulator. We will show system functionality and efficiency during the execution of some basic functional movements.
