Soft Active Back Exosuit to Reduce Workplace Back Pain

The back exosuit is a soft wearable robotic suit designed to improve a wearer physiology, kinetics, kinematics to reduce the possibility of injury. The back exosuit is primarily composed of textiles that wrap around an individual's shoulder (backpack) and thighs (thigh wrap) to serve as anchor points. An actuating element attaches to those anchor elements to provide assistive forces while the user performs a physical activity. The soft wearable robot integrates sensing components to be able to detect user biomechanics and device function and actuating elements via algorithms that command the actuation based on users' intent. To encourage usability, the device is easy to don and intuitive to use. This back exosuit has demonstrated significant reductions in back (18%), hip (11%) and knee (22%) extensor muscle activity during a 1-hour workplace simulation task when compared to lifting without a suit.
