As a major highlight of the "Texas A&M University @ NTU 2026" visiting program, Prof. Toru Tanzawa from Waseda University (Japan) was invited to deliver a distinguished lecture at NTU on May 28. In his presentation titled "Toward the Smallest and Lowest-Cost AC-DC Converters for Vibration Energy Harvesting," Prof. Tanzawa shared his latest breakthroughs in energy harvesting technologies, particularly for IoT sensor applications. He detailed how fully integrated AC-DC and switched-capacitor converters using CMOS technology can significantly reduce circuit area and eliminate the need for large external components like inductors. This innovation provides an exceptional solution for achieving low-cost, small-form-factor, and battery-less IoT devices. As a co-organizer, NTU RTRC is proud to support this international academic exchange. Prof. Tanzawa's profound insights are expected to inspire new perspectives and drive research momentum in low-power IC design and green energy conversion technologies within Taiwan's academic community.
