Micro electromagnetic and piezoelectric transducers are key microdevices for energy conversion and signal sensing, widely used in ultrasonic imaging, structural health monitoring, and MEMS applications. Their operation is based on electromagnetic induction or the piezoelectric effect, enabling efficient coupling between mechanical vibration and electrical signals. Our research focuses on integrating advanced micro/nanofabrication technologies with novel functional materials to develop high-sensitivity, low-power, and broadband transducer arrays.

These devices offer advantages such as high integration capability, suitability for miniaturized and wearable systems, as well as high precision and real-time responsiveness. However, several challenges remain, including maintaining energy conversion efficiency at extremely small scales, enhancing signal-to-noise performance, and ensuring long-term stability under complex operating conditions. Students working in this direction will gain interdisciplinary expertise spanning materials science, microfabrication, and electromagnetic/acoustic modeling.
