HOY TV Features Life-Changing Medical Innovation by Prof. Haw-yaw TAM and his team

HOY TV’s acclaimed health program Health Concern Group (《健康關注組》) recently spotlighted a transformative medical innovation developed by Professor Haw-yaw TAM and his distinguished EEE research team. The pioneering “Ultrafine High-Sensitivity Optical Fibre Sensor”—honored with dual awards at the 50th International Exhibition of Inventions Geneva. —is poised to redefine precision in cochlear implant surgery. Addressing a critical limitation of traditional rigid glass fibers used in delicate procedures, Professor TAM’s team engineered an innovative, flexible, ultra-thin plastic optical fiber sensor. This technology provides surgeons with real-time, high-precision feedback during complex inner-ear surgeries. Its design earned it two prestigious honours at the exhibition: the “Thailand Award for the Best International Invention & Innovation” and a “Gold Medal with Congratulations of the Jury.” This breakthrough offers unprecedented control over electrode placement and simultaneously monitors the contact force of the electrode, enhancing surgical navigation while dramatically reducing the risk of tissue damage. These advantages translate into profound benefits for patients: safer procedures, optimized hearing restoration through precise implant positioning, and expanded treatment possibilities. We extend our heartfelt congratulations to Professor TAM and his dedicated team on this remarkable achievement, which proudly representing our department on the world stage.   Watch the Full Interview Here: HOY TV-TV Programme Health Concern Group (《健康關注組》) Episode 373 https://lnkd.in/eBy6D-in
