Research Interests

Professor Chen develops the next generation of sensors, actuators, energy conversion and storage devices by using novel nanostructured and bio-inspired functional materials. His recent work on water-responsive materials and evaporation-driven engines opens up a new field in energy harvesting and provides opportunities towards solving current challenges in sustainable energy, energy storage, clean water, robotics, and medical technologies.
