Jointly developed by Dr Raymond Tong Kai-yu, Associate Professor of the Department of Health Technology and Informatics, and the Industrial Centre, this Exoskeleton Hand Robotic Training Device works to recover the hand functions of stroke patients. It is made up of an embedded controller and a robotic hand module, which provide patients with assistive power to perform hand movements and gradually boost relearning in the brains of stroke patients.

One the compact, wearable robotic hand is attached to the patient’s fingers and hand, it begins to detect his or her intention to move through signals from the hemiplegic side measured by surface electromyography. A nervous response then set the robotic hand in motion to move the patient’s stiff hand at his or her own will. The device affords substantial flexibility, as each finger assembly can be adjusted to fit different finger lengths.
Unlike the case with conventional rehabilitation treatment, the assistive power from the robotic hand helps to overcome muscle and joint stiffness, thus allowing the patient to open/close a paralysed hand or pick items up according to his or her own intention. Through repetitive exercises, the hand motions send feedback to the patient’s brain, helping it to rewire itself in response to new experiences.
The device has been licensed to the Deltason Medical Group, and clinical trials are well underway at the Shatin Hospital and Kowloon Hospital. It also won a Gold Medal at the 62nd International Trade Fair Ideas – Inventions – New Products in Nuremberg, Germany.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
