This article considers current technical trends, challenges and solutions being used to update the capabilities of PoE with the drive towards delivering increased power remotely via Ethernet infrastructure.
Low-power microcontrollers have done much to improve longevity in energy-harvesting systems.
Powered by ambient energy, "zero-power" wireless sensors find application in nearly every market segment.
Energy budgets are one of the biggest challenges in the design of remote sensing and control platforms.
Micro-harvesting, or energy scavenging, relies on extracting power from minute but pervasive sources of ambient energy such as light, heat, RF, or vibration.
Supercapacitors offer performance characteristics that are suited for energy-harvesting environments.
