The document discusses energy harvesting solutions from Spansion to eliminate the need for batteries and fuel the Internet of Things. It introduces the MB39C811 and MB39C831 power management integrated circuits (PMICs) that can harvest energy from light, vibration, and heat to power wireless sensor nodes and other devices. Evaluation boards and a starter kit are also described to help developers test energy harvesting solutions using these new PMICs.

Energy Harvesting – Eliminates the Need for Batteries
and Fuels a Greener Environment
ENERGY HARVESTING is essential in
converting ambient energy – such as light,
vibration, thermal and radio waves – into
electricity for a wide range of applications.
It will be used for battery-less product
development or supporting battery charging.
