Prof. TAM Haw Yaw’s “Hearing Hope” Project Wins Top Honors at International Exhibition of Inventions Geneva

Prof. Tam Haw Yaw has been awarded the Thailand Award for the Best International Invention & Innovation and the Gold Medal with Congratulations of the Jury at the 50th International Exhibition of Inventions Geneva (Geneva Inventions Expo). These accolades recognize his ground-breaking project, “Hearing Hope: A Smart Sensor for Enhanced Safety and Precision in Hearing Restoration Procedures.” Prof. Tam Hwa Yaw (left) and Dr Cui Jingxian (right) at the award ceremony.   Prof. Tam, who serves as Chair Professor of Photonics and Associate Director of the Photonics Research Institute (PRI), developed a smart sensor-integrated cochlear implant (CI) system that enhances the safety and precision of cochlear implantation surgeries, the primary treatment for severe to profound sensorineural hearing loss. Current surgery procedures lack real-time feedback on CI positioning and contact force during insertion, risking tissue damage and suboptimal outcomes linked to cognitive decline and socioeconomic barriers. Dr Cui presented the invention to visitors. Prof. Tam’s team integrated polymer optical fiber sensors into electrode arrays of the CI, enabling real-time, high-resolution monitoring of contact force and precise spatial localization during cochlear implantation surgery. By providing surgeons with critical tactile and navigational feedback, the system aims to minimize intracochlear trauma, improve placement accuracy, and enhance postoperative outcomes. Prof. Tam and his team showcased the invention.   10x scale model of cochlear implant electrode array positioned in the scala tympani of the human inner ear.   “Our goal is to transform cochlear implantation surgery into a safer, reproducible procedure,” said Prof. Tam. This innovation also lays the foundation for robot-assisted CI, promising standardized precision, reduced costs, and expanded access to this transformative procedure, particularly in resource-limited regions.   Celebrating its 50th edition, the Geneva Inventions Expo attracts over a thousand entries from nearly 40 countries and regions. By merging photonics, medical engineering, and data analytics, Prof. Tam’s team highlights how interdisciplinary innovation can tackle pressing human challenges, turning scientific breakthroughs into tools for hope. Prof. Tam and his team were awarded the Thailand Award for the Best International Invention & Innovation and the Gold Medal with Congratulations of the Jury.

Awards at the 4th Asia Exhibition of Innovations and Inventions Hong Kong

We are pleased to share that the project “Highly integrated wireless ultrasonic motor system for fully enclosed environments”, led by Prof. Chau Kwok-tong, was awarded the Grand Prize and a Gold Medal at the 4th Asia Exhibition of Innovations and Inventions Hong Kong organized by The Hong Kong Exporters’ Association on 5-6 December 2024! Dr Liu Wei also won a Silver Medal for his project “High-efficiency GaN converter module for wireless power transfer facilities” in this exhibition. The wireless ultrasonic motor system designed by Prof. Chau’s research team features a single integrated magnetic coupler connected to the motor, which can control motor systems in fully enclosed environments without power cables, batteries and controllers. The system is adaptable to various applications, facilitating seamless integration. Its streamlines are designed by operating without additional controllers or sensors, which is ideal for environments where traditional cabling is impractical, such as in robotic arms, enhancing mobility and flexibility. In enclosed environments like underground pipelines or underwater propellers, it avoids complications from perforated installation cables, preventing gas or liquid leaks. This innovation brings new solutions for advanced applications in robotics and industrial automation. Dr Liu’s team has integrated gallium nitride (GaN) chips into the design of high-performance power converters with low gate driver stray inductance and low switching loss. An insulated metal substrate printed circuit board design is utilised to lower the thermal resistance while ensuring electrical isolation. The gate drive has small ringing and voltage overshoot, which ensures the realisation of smooth switching characteristics of the GaN switches. Compared with other converters, the new GaN high-electron-mobility transistor (HEMT) converter has higher efficiency, power density and switching frequency. Compared with GaN converters at the same power level, this new converter has better drive performance and incurs lower costs to promote commercialisation. It can be applied in various wireless power transfer facilities, including wireless charging for electric vehicles among others.
