DEMETER Series of Piezoelectric
Energy Harvesters

Energy harvesting means generating energy from available environmental energy. This allows, for example, wireless data transfer to be performed without requiring batteries. Piezoelectric energy harvesting makes use of the direct piezoelectric effect to convert elastic (mechanical) energy to electrical charge.

Enclosure-integrated DEMETER energy harvesting modules incorporate matching KIRKE state-of-the-art power transfer circuitry enabling high efficiency solution to energy scavenging in a small, simple to install, fully integrated module. These are available either with or without a pre-installed LiSO4 battery storage capability and include (battery) connections.

Novel DEMETER design modifications of its piezo-beam harvester technology now address applications where the primary concern is efficient conversion of much of the (low/mid acoustic frequency) ambient shock and vibration energy.

QorTek wiring is specifically manufactured for these piezoelectric energy harvesting applications.  Constructed of few strands of thin gauge coated transformer wire it provides an extremely, flexible, thin, and lightweight conductive path to the piezoelectric scavenging devices.

QorTek uses custom developed machining techniques to produce thin flat
Piezoelectric beams that can include tip mass for lower frequency coupling.
These are available as bare devices or as fully integrated rugged units.
