The Synapsuit is a research project aimed at developing a powered exoskeleton device that uses an electrostatic clutch system to reduce muscle fatigue caused by functional electrical stimulation (FES). The electrostatic clutch technology, currently being prototyped by the Korea Electronics Technology Institute (KETI) in South Korea, is designed to hold a user’s joints in place between FES-driven movements. The clutches are flexible sleeves placed around the user’s elbows, wrists, and knuckles that can be rapidly stiffened when a voltage is applied to the flexible conductive plates inside the sleeve. This eliminates the need for continuous muscle stimulation just to hold a joint in place.
The Synapsuit team, led by Kyuhwa Lee of the Wyss Center for Bio and Neuroengineering in Geneva, envisions a neural interface for their assistive system in the future. Another team is currently developing neural electrodes for this purpose. However, the electrostatic clutch and neural-decoding software required to control the Synapsuit are still prototypes, and human trials on Neurosoft’s flexible neural electrodes have just begun. Despite this, Lee expects the overall project to produce a functional Synapsuit system by 2026.
Exoskeleton suits are wearable devices that enhance human strength and performance. The exoskeleton industry is expected to grow significantly from $68 million in 2014 to $7.3 billion by 2030. Logistics and manufacturing industries are key markets for exoskeletons due to their use in heavy lifting and extended tasks. The military is also expected to play a larger role in the market as they fund research into exoskeleton applications. Top manufacturers include Comau, Cyberdyne, Ekso Bionics, German Bionic, Hyundai Motor Group, Lockheed Martin, Ottobock, ReWalk Robotics, Sarcos Robotics, and Wandercraft.
