Rui Xu

Rui Xu is a Researcher at the McGovern Institute for Brain Research at the Massachusetts Institute of Technology (MIT). His work focuses on advanced energy harvesting technologies, particularly leveraging MEMS (Micro-Electro-Mechanical Systems) and piezoelectric materials to capture energy from low-frequency vibrations and human motion. Key research areas include wearable energy systems, combat boot-based energy harvesting for satellite positioning, and innovative sensor designs using carbon nanotube fibers.

His research interests span the development of sustainable energy solutions through miniaturized MEMS devices, bi-stable beam mechanisms, and airflow-induced energy conversion. Xu's contributions emphasize practical applications in wearable technology, military systems, and low-power sensor networks. He has explored the integration of porous lead-free materials and flexible nanogenerators to enhance output voltage and system durability.

Notable projects include low-frequency vibration harvesters with buckled beams and studies on heel-strike induced airflow for human activity sensing. His work bridges mechanical engineering, materials science, and electrical engineering, aiming to improve energy conversion efficiency in challenging environments.
