Vibration
Energy Harvesting

Do you want your device to recharge from a vibration source without the need to change the battery? Then, discover our vibration energy harvesting AEMs.

Is 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 human, a motor, a train, the vibration of a machine, etc.

You (or you customers) need to re-place the batteries of these devices, because they run out of energy. This generates operational costs and a negative impact on environment

Depending on the frequency of the vibration, piezo vibration harvester can generate 4 µW/cm² from a human and 250 µW/cm² from a machine while an electromagnetic harvester can generate 50 µW/cm³ from a human and 2 mW/cm³ from a machine

Best performing Ambient Energy Manager IC AEM30940 for vibration energy harvesting, enabling your devices to get supplied by a movement, a vibration or a current AC signal. Dedicated support to help you define the required vibration harvester and the storage element size
