Vibration

Overview

IS E-PEAS’ VIBRATION ENERGY HARVESTING FOR YOU?

Let’s assume that you work with battery-powered IoT wireless devices that operate in an environment presenting constant vibration generated by a motor, a train, the vibration of a machine, etc. Without energy harvesting, you need to replace the batteries of those devices, because they run out of energy. This generates operational costs.

But, in some environments, there is enough of energy dissipated by surrounding machines or objects that you could use to power your devices.

Depending on the frequency of the vibration, vibration harvester can generate 15mW to 500mW.

When properly selected (material and topology) and sized (vibration frequency), a vibration harvester combined with our state of the art energy harvesting PMICs will recharge the batteries of your IoT applications.

Using e-peas’ vibration energy harvesting, you will avoid typical operating costs associated with battery replacement.

WHAT EXACTLY DO WE OFFER?

Best performing solutions that make your devices’ batteries live forever. Our innovative ICs autonomously and efficiently recharge your batteries from any temperature gradients.

e-peas offers you 1 AEM [Ambient Energy Manager] reference:

  • The AEM30940 allows you for harvesting energy from vibration producing from 3µW up to 550mW.

HOW DO WE DIFFER FROM COMPETITION?

This reference is based on e-peas unique AEM platform offering:

  • top energy conversion efficiency
  • the fastest supercapacitor charge
  • the lowest cold-start power
  • the smallest footprint and associated components BOM

In addition, you will get direct access to engineering support by our designers.
