Energy Harvesting
In the field of liquid detection, many challenges exist, including wiring complexity, battery replacement burdens, and power supply difficulties.
Asahi Kasei Microdevices (AKM)’s proprietary technology enables electronic devices to operate without batteries or external power sources by boosting and utilizing small amounts of energy from water droplets and liquids. This enables long-term operation and greater installation flexibility, expanding applications beyond infrastructure monitoring to the industry relating to safety in daily life and various other fields.
This page introduces examples of how the technology is being applied.
Chemical power generation (power generation from a few drops of water)
Power Generation with a Few Drops of Water
Using a step-up DC-DC converter, water droplets and a wire, the energy produced by the chemical reaction between water and metal is harvested.
