Energy Harvesting
Contributing to the realization of a system that does not use primary batteries
Asahi Kasei Microdevices Corporation (AKM) contributes to the development of a primary-battery-free system through its original energy harvesting circuit technology.
The Energy Harvesting IC of Asahi Kasei Microdevices Corporation (AKM) is ideal for gathering small amounts of ambient energy, such as indoor light and natural body heat.
It does not require replacement of batteries and contributes to miniaturization of IoT devices as well as wireless communication.

Power supply using a secondary battery and a capacitor
AKM's Energy Harvesting IC enables system startup in a short time by charging from an environmental power generator to a small-capacity capacitor. If the voltage of the capacitor rises after system startup, the IC connects the capacitor and the secondary battery and starts charging the secondary battery.
Therefore, it is possible to start the system without waiting for a long time to charge the secondary battery.
