Abstract
The present invention relates to a wearable device using a flexible non-powered variable impedance mechanism, wherein the device can induce a user to have a correct posture during a squat exercise or lifting work, and can assist the user's muscular strength. According to the present invention, an angle between a (1-1)th lower string and a (1-2)th lower string and an angle between a (24)th lower string and a (2-2)th lower string change according to a knee angle depending on the user's posture, whereby an impedance mechanism that the user feels through the body changes.
