Wearable Smart LED Device for Knee Osteoarthritis
Principal Investigator: Prof. Amy FU
Award: Bronze Medal at the 4th Asia Exhibition of Innovations and Inventions
Knee osteoarthritis affects many in ageing and athletic groups, with limited long-term treatments. This wearable LED device, featuring temperature sensors, differentiates knee osteoarthritis phenotypes for targeted therapy. Animal studies reveal that each wavelength targets specific tissues like synovitis, tendons, or cartilage. Its three-chip LED customises treatment, while an AI system optimises settings. Patients receive personalised rehab advice and virtual consultations via QR code.
Patellar Auto-Mobilising Device (PAD)
Award: Gold Medal at the 49th Geneva International Exhibition of Inventions
The PAD addresses patellofemoral pain syndrome by automating patellar mobilisation with negative pressure. It consists of an air-sealed knee cap, a mini vacuum pump, a control circuit, an elastic garment
suspension mechanism, and a rechargeable battery. The PAD is worn on the knee and creates personalized negative pressure to separate the patella from the femur, thereby relieving pain and enhancing movement. Moreover, the PAD offers various modes, which hold and release the negative pressure at different intervals for different conditions, and allows knee movement under negative pressure, which improves mobility and provides effective pain relief.
System for Evaluation and Triage for Healthy Knees
Award: Silver Medal at the 48th Geneva International Exhibition of Inventions
A new smart ageing solution uses a mobile app to improve the quality of life for older adults by promoting early disease identification, encouraging healthy living, and reducing medical burdens. The app utilises vision computing technology to assess physical health and the risk of degenerative diseases through simple tests. It measures knee health data and categorises users into different risk groups, providing tailored exercise programmes and regularly tracking progress to evaluate and monitor knee health.
Powered Rehab Skateboard
Award: CES Innovation Awards 2026 Honoree in the “Accessibility and Longevity” category
Designed for stroke patients with upper limb impairment, this innovative technology is a portable and cost-effective robotic system that enables effective home-based therapy. The device supports motor recovery in hemiparetic upper extremities by guiding users through precise, controlled movements. It offers multiple operational modes, including passive, assistive, and resistive, to suit different stages of rehabilitation. A key feature of the skateboard is its integrated torque sensor, which detects the user’s active force in real time and automatically adjusts the level of assistance, ensuring personalised and optimal support throughout the recovery process. Its compact design allows patients to continue therapy at home, reducing the need for frequent clinical visits and improving accessibility to rehabilitation.
“Remind-to-Move” Sensory Wristband
Principal Investigator: Prof. Kenneth FONG
A tele-rehabilitation system comprises a first wearable configured to be worn on an affected upper extremity of a user, a second wearable configured to be worn on an unaffected upper extremity of the user, a mobile application platform, a therapist platform, and a rehabilitation controller. The mobile application platform receives kinematic data from the first and second wearables and inform ‘remind-to-move’ pattern to the user. The therapist defines at least one reminder setting for the user. The rehabilitation controller is switchable between an open-loop mode, in which an output interface of the first wearable provides a sensory reminder cue at a predetermined time interval, and a closed-loop mode, in which the output interface provides the sensory reminder cue according to a threshold-based algorithm that compares activity of the affected upper extremity with activity of the unaffected extremity to determine whether the sensory reminder cue should be postponed.
