This technology is a wind energy harvester combining vortex-induced vibration (VIV) and MEMS-based piezoelectric conversion. It features low wind speed activation, modular design, and high integration. Cylindrical arrays enhance vortex interaction, boosting power output. Suitable for powering IoT sensors in off-grid areas, the device is patented in Taiwan and the U.S., and has potential for green energy modules in smart buildings and environmental monitoring.

This technology pioneers a MEMS-scale vortex-induced vibration (VIV) energy harvester capable of operating under low wind speeds (<1.5 m/s). With a compact 10×10 mm² footprint, it  achieves amplified vibrations via a lock-in effect and leverages a multi-cylinder array to induce synergistic vortex excitation, significantly enhancing energy output. This breakthrough overcomes key limitations of microscale VIV systems and enables deployment across diverse smart sensing applications.

This technology suits IoT, smart buildings, and remote monitoring, featuring low wind-speed startup, high integration, and mass production potential. Its compact size fits dense sensor networks, ideal for structural health, agriculture tracking, and environmental sensing. With low wind speed starting, it supports off-grid or hard-to-reach sites and lowers maintenance. Integration with low-power communication modules promotes sustainable, low-carbon smart cities aligned with ESG goals.
