Soft Robotics Helps Caregivers Preserve Skeletal Health

The energy required comes from the wearers themselves, through their movements. When a caregiver bends down to lift a patient up, the smart medical aid stores the kinetic energy and can release it again when required.

The smart vest features a myriad of sensors that continuously monitor the way the wearer is moving, and a processor compares these data against the optimum movement pattern as dictated by ergonomic guidelines. As soon as it detects any irregularity, a warning lamp is activated, indicating the movement may be harmful. Not only that, but innovative synthetic actuators with adjustable rigidity help avoid incorrect movements and support correct ones. For example, the vest warns the user when he is lifting something heavy with a rounded back, instead of squatting down to lift the object with a straight back.

“Until now, there haven’t been any efficient support systems to help caregivers with the heavy work they encounter in their extremely varied day-to-day work,” said Henning Schmidt, who heads the project for IPK. “A prototype of the vest should appear in 2015. It’s not just caregivers who could make use of this sort of active support, but anyone performing heavy physical work – construction workers, roofers, garbage collectors, brick layers and many more.”
