Innophys Muscle Suit Every

Overview

The Muscle Suit Every is a back-assist suit from Innophys, a Tokyo University of Science spinout, and it works very differently from motor-driven exoskeletons. It has no motor, battery or electronics; instead the wearer pumps air by hand into McKibben-type pneumatic artificial muscles, which then pull to help straighten the back during lifting, up to 25.5 kgf (100 Nm). That makes it light (3.8 kg), cheap for the category at about $1,000, rated IP56, and usable from -30 to 50 °C, with an endurance test of 400,000 cycles, but the assist is a fixed spring-like pull rather than a sensed, timed push. It is sold to care homes, farms, factories and logistics sites as well as to individuals for jobs like snow clearing, and the series has passed 35,000 units shipped. A lighter Every-Light (3.1 kg, 20 kgf) joined the range with monitor sales from Sep 30, 2026 (unconfirmed). Motor-driven rivals such as the ATOUN Model Y cost several times more.
