Special design and mechanism

• The device, consists of two fabric sections, made of nylon canvas,
• Lycra, polyester and other materials, for the chest and legs.
• The sections are connected by sturdy straps across the middle back,
• with natural rubber pieces at the lower back and glutes.
• The device is designed so that users engage it only when they need it. A simple double tap to the shirt engages the straps.
• When the task is done, another double tap releases the straps so the user can sit down, and the device feels and behaves like normal clothes.
• The device also can be controlled by an app that the team created –
• users tap their phones to engage the smart clothing wirelessly via Bluetooth.
• In experiments, the participants tested the device leaning forward and lifting 11-kg and 25-kg
• weights while holding their position at 30, 60 and 90 degrees.
• Using motion capture, force plates and electromyography, the team demonstrated that
• the device reduced activity in the lower back ex tensor muscles by an average of 15 to 45 per cent for each task.
• The focus of this new technology is not for treating those with existing back pain but
• focuses on prevention by reducing stress and fatigue on the low back muscles, Yang said.
