A research team led by Associate Professor Cheng-Hsin Hsu of the Department of Computer Science and Information Engineering received a Gold Medal for its innovative technology, the “Pronunciation Correction System for Individuals with Hearing Impairment” (Patent No. I863882). The system establishes personalized hearing thresholds through pure-tone audiometry and enhances sounds within affected frequency ranges. It integrates original audio, processed audio, and recording exercises with personalized hearing compensation and speech recognition to provide a comprehensive pronunciation assistance process. Users can complete hearing tests, listening exercises, imitation, recording, and speech recognition within a single app. An Android app prototype and integration of the major functional modules have been completed.
A research team led by Professor Chung-Wen Hung of the Department of Electrical Engineering received a Silver Medal for its innovative technology, the “Concrete Water-Cement Ratio Detection System and Method” (Patent No. I896307). The system uses a microcontroller integrated with a microphone and a three-axis accelerometer, together with an automated tapping device, to rapidly collect sound frequencies and vibration waves from test specimens. By combining audio and vibration-wave measurement technologies with data processing, artificial intelligence, and edge computing, the system can reduce the technical barriers and costs associated with testing. Smaller and more portable than conventional testing machines, the invention can be offered as a rental service or developed as a commercial product.
A research team led by Professor Yi-Chang Wu of the Department of Mechanical Engineering received a Silver Medal for its innovative technology, the “Magnetic Gear Mechanism and Rope-Winding Device” (Patent No. I938103). Designed in response to the high wear associated with conventional gears and the need for efficient power transmission, the magnetic gear system enables non-contact power transmission, magnetic overload protection, and multi-stage gear-ratio changes directly between gears. As an innovative alternative to conventional gearing, the technology addresses several limitations of traditional winches, including the inability to adjust operating force, inadequate protection against excessive loads, and the need for lubrication and maintenance.
The technology has undergone extensive development and testing and has demonstrated stable operation. Compared with conventional winches, it offers high efficiency, ease of operation, and lower maintenance costs. Its standardized components and simple structural design also contribute to low production costs and make mass production feasible. The invention effectively addresses common problems associated with traditional winches, including excessive noise, rapid wear, difficulty in adjusting operating force, and low efficiency, giving it strong market competitiveness and economic potential.
A research team led by Professor Shih-Ying Chang of the Department of Mechanical Engineering received a Silver Medal for its innovative technology, the “Joining Filler Alloy Layer and Joining Method” (Patent No. I926716). In response to the thermal management and high-temperature reliability requirements of high-power components used in aerospace, electric vehicles, radar, satellites, and communication systems, the team developed a Zn-Al-Cu-Ag filler alloy capable of rapid joining under atmospheric conditions. By utilizing the high-temperature solid-solution characteristics of aluminum-zinc and copper-zinc systems, the technology enables reliable joining of aluminum, copper, and high-thermal-conductivity dissimilar materials.
When applied to graphene-copper/AlSiC joining, the technology achieves shear strengths of 32.77 MPa at room temperature and 21.89 MPa at 500°C. When applied to graphene-copper/aluminum alloy joining, it forms a dense joining layer with nearly zero interfacial thermal resistance, achieving a maximum thermal conductivity of 446 W/m·K. The technology is suitable for high-power module packaging and advanced thermal management applications.
