About

Hyung-kwan Chang is a pioneering researcher in the interdisciplinary field of bio-microelectromechanical systems (bio-MEMS), with a primary focus on developing innovative power generation technologies that harness biological tissues. His most notable contribution is the design and fabrication of a MEMS-based power generation system that utilizes the contractile force of self-organized cardiomyocytes—heart muscle cells—to produce electrical energy. This groundbreaking work, published in 2010, has garnered 9 citations and represents a novel approach to integrating living biological actuators with micro-scale mechanical systems. By demonstrating that cultured cardiac cells can be organized into functional tissue constructs capable of generating measurable power, Chang opened new avenues for bio-hybrid energy harvesting and micro-robotics. His research sits at the intersection of tissue engineering, micro-fabrication, and energy conversion, offering a unique perspective on how living systems can serve as sustainable micro-power sources. Chang's work is particularly relevant for students and researchers interested in bio-inspired engineering, lab-on-a-chip technologies, and the future of implantable medical devices that could one day be powered by the body's own cells.
