Company Profile (Virginia Tech (CEHMS))

Virginia Tech (CEHMS) logo
Center for energy harvesting materials and systems (CEHMS) addresses an important problem of our generation facing the sensor networks, wireless communication and microelectronics industry related to power source. CEHMS aims to lead the global research and development in the area of energy harvesting by providing comprehensive expertise in all the related aspects including materials, components, system design, analysis, characterization and prototyping. We will discover new methods to create electricity and invent technologies that allow transitioning the prototypes to society. CEHMS has the mission of providing integrated solutions to microelectronics, mobile and wireless technology problems through modeling, analysis, fabrication and demonstration of intelligent systems. The devices developed at CEHMS will provide the architecture for "self-powered sensors" and open the pathway for distributed power sources. CEHMS addresses multiple industries and will have access to wide spectrum of manufacturers, and suppliers. The research at CEHMS covers development of harvesters utilizing single and multimodal conversion mechanisms, adaptive energy harvesting circuits, intelligent energy management system, and conformal storage media. Our access to cutting-edge facilities at three campuses allows us to explore various challenging industrial problems in an timely and efficient manner.
