Replication and Advancement of a Functional Electrical Stimulation Device: A Practical Guide

In medical rehabilitation, electric stimulation has always been significant. Though it is not a novel technique, Functional Electronic Stimulation (FES) requires improvement through ongoing research and development. This need for continuous improvement compounds when creating an implantable device. As implantable devices pose additional complex challenges, a thorough investigation is required to ensure the most efficient utilization of FES. Following Jarvis and Salmons' original work, this paper examines the developments and difficulties involved in creating FES devices. We introduce improvements to the Jarvis and Salmons original circuit that will maximize power efficiency, prolong battery life, and increase durability. Our innovative technique developed a printable circuit board (PCB) that requires little interference during implantation and is powered by a single lithium-ion coin cell battery. By resolving concerns with PCB manufacture and functioning, our suggested improvements will advance the field of medical rehabilitation by providing useful information for the deployment of FES devices.
