From robotic gloves to safer batteries, CUHK puts research to work

HONG KONG — From helping stroke patients perform everyday tasks to developing safer ways to store electricity, researchers at The Chinese University of Hong Kong (CUHK) are developing technologies for use beyond the laboratory. During a visit to the university on Sept. 1, a reporter tried on a robotic glove that moved the fingers with noticeable force, but without jerking them. For stroke survivors who cannot move their hands, that movement could help them do something as ordinary as holding a spoon or picking up a phone. The device uses air-powered artificial muscles developed by a team led by Raymond Tong, a professor of biomedical engineering at CUHK. Unlike conventional motor-driven rehabilitation equipment, the lightweight system uses a small pump to help patients open and close their hands. “Nowadays, you can see those exoskeletons are very rigid. They are very heavy,” Tong said, inviting the reporter to try the device. Patients can use it both for rehabilitation exercises and everyday tasks, including gripping objects, writing and eating. Tong said the system can also respond
