Sensors will be on our bodies, our pets, in remote fields and they will have to run for many years on small batteries or utilizing energy harvesting techniques.” Solution: “This class will teach attendees how to implement energy harvesting in an application. We will discuss examples of energy harvesting sources, storage methods, explain concerns for energy harvesting applications, and demonstrate how to use an RL78 MCU to solve these problems. ” ‘Enabling The Smart Society’ © 2012 Renesas Electronics America Inc.
