Abstract

The concept of converting human energy into useful power by various mechanisms has been explored as an alternative way to support the operation of implantable bioelectronics. Triboelectric nanogenerators (TENGs) have recently been proposed as a promising technology to harvest energy as an alternative power source for these implantable devices. In this paper, we investigate stacked TENGs as a potential power source for peripheral nerve stimulation. To achieve sufficient electrical energy for the stimulation, we optimize various parameters of the stacked TENGs. We combine the optimized TENGs and neural electrodes to demonstrate batteryless neural interfaces. We conduct direct and selective stimulation of sciatic nerves in rats using this batteryless neural interface to modulate different muscle activation. This prove-concept result indicates that this technology could enable a self-sustainable platform for neuromodulation in the future.
