Energy Harvesting
There are many different types of energy sources around us, including thermal, chemical, optical, vibration, and radio frequency. Asahi Kasei Microdevices (AKM) offers solutions for utilizing all of these energy sources with its multiple products.
Power Generation at the Touch of a Finger
Using an AP4473 step-up DC-DC converter for thermal energy and a Peltier element, the AP4473 harvests thermal energy at the fingertip (body temperature).
Power Generation with a Few Drops of Water
Using the AP4470 step-up DC-DC converter, water droplets and a wire, the energy produced by the chemical reaction between water and metal is harvested.
Light energy can be collected even without solar cells
Light energy from LED lighting is collected using a step-up DC-DC converter AP4470 and a photodiode.
Can drive systems with high power consumption even by using indoor light
Even if the power harvested is small, a system with a large power consumption can be driven by increasing the time of collection.
The performance of the generator used and the power obtained by the step-up DC/DC converter can be calculated in Web Sim (designed support).
