Energy Harvesting

AKM's step-up DC-DC converters generate power from a small amount of environmental energy that exists around us. For example, electricity can be generated by extracting heat energy from body heat or from chemical energy by dripping a few drops of water on to a wire.

Here is an example of power generation achieved by combining AKM's step-up DC-DC converter and environmental energy.

AKM's step-up DC-DC converters are available in several lineups to allow power generation with various types of generating elements. In the "Find a Product" section, you can select a product by the performance of its power generating elements.

A simulator that can calculate the power available from any generating element and AKM's step-up DC-DC converter. It can be used to estimate the environmental energy harvesting time when considering a system.

Until now, small amounts of environmental energy around us have been discarded without being harvested and AKM's unique circuit technology has enabled the harvesting of a small amount of this environmental energy by incorporating a "voltage booster circuit that starts up at only 15[mV]" and a "charge/discharge control circuit that operates at only 86[nW] of the harvested energy" into a single chip.  Reasons to choose AKM's step-up DC-DC converters are explained in the "Reasons to choose AKM" section.
