Improvement of Lower Back Support Exoskeleton: Muscle Suit "Every"

Lower back pain (LBP) is a common problem addressed among adults working in physically demanding environments. As a countermeasure, we have developed the Muscle Suit series, an assistive device designed for waist support. In 2019, we launched the mass-produced model "Every", making the product more accessible by reducing the price from over 500,000 yen to 100,000-yen range, and more than 20,000 units have been shipped to date. However, many users have requested improvements in terms of size, weight, and ease of walking. This report introduces the major points of improvement we have made to Every to meet these user’s demands.
