Here is a soft wearable robotic suit that promotes normal walking in stroke patients. Researchers at the Wyss Institute for Biologically Inspired Engineering, the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and Boston University’s (BU) College of Health & Rehabilitation Sciences: Sargent College developed this lightweight wearable ankle-assisting exosuit for gait re-training. As they explain:
Exosuits are anchored to the affected limb of a hemiparetic stroke patient via functional apparel, and they provide gait-restoring forces to the ankle joint by transferring mechanical power via a cable-based transmission from battery-powered actuators that are integrated into a hip belt or an off-board cart located next to a treadmill.
This robotic suit is programmable and virtually invisible. You can find out more about it here.
