E-821 Energy Harvesting Module

In addition to the transducer and storage electronics, the E-821.EHD evaluation kit contains the required cabling and corresponding DuraAct piezo transducers for the integration in an application. The output voltage of between 1.8 and 5 V can be used to operate commercially available electric circuits and systems  

The E-821 energy harvesting electronics is designed to work best with P-876 DuraAct patch transducers  

To dimension an energy harvesting system correctly, all important boundary conditions must be known and taken into account. The principle itself is simple: Ambient vibrations produce a charge separation in the piezoceramic DuraAct transducer. The electronic circuitry in the E-821 module then ensures a sufficiently stable output voltage that can be adjusted to the load  

DuraAct patch transducers, which are available in many different designs, can be adapted to the application

For generating energy from vibration. Use in combination with DuraAct patch transducers. Adjustable output voltage. Processes input currents between 20 µA and 40 mA, voltage peaks are limited to 15 V. Custom version for operation with piezo stack actuators on request

Autonomous power supplies, e.g. for wireless sensor networks
