What is a Volture Vibration Energy Harvester?
What are it's vibration energy scavenging advantages?
The Volture is a robust, reliable and inexpensive means to harvest vibration energy for you application! The Volture vibration energy harvester device harvests otherwise wasted energy from mechanical vibrations. The Volture accomplishes this by using piezoelectric materials to convert mechanical strain into useable electrical energy. The Midé Volture energy harvester is unique because it incorporates Midé's patented QuickPack Piezoelectric transducer technology. Through a proprietary manufacturing process, the QuickPack transducer packages piezoelectric materials in a protective skin with pre-attached electrical leads, producing a highly reliable component with no soldered wires. The QuickPack actuator's protective skin also provides electrical insulation and defense against humidity and harsh contaminants.
What is a Raw Volture Vibration Energy Harvester?
Mide currently offers six energy harvesting products. Both the PEH20W and PEH25W include power conditioning electronics as well as an anodized enclosure with integrated clamp. When you order a raw energy harvester, the V20W, V25W, V21B, or V21BL, you will just receive the packaged piezo energy harvester with pre-routed mounting holes and connector. You will NOT receive the power conditioning electronics or anodized case with integrated clamp. This product is good for "testing" the technology and seeing how it will fit into your application.
What are Energy Harvesting Electronics?
The output from a cantilevered piezo element in the presence of a vibration is sinusoidal or AC (alternating current). Most sensors that would be powered by an energy harvester require DC (direct current) power. Thus the raw AC output from the piezo needs to be converted from AC to DC. This process is done using a simple rectifying circuit. Midé currently offers two forms of its power conditioning electronics, the ehe001c has a capacitive storage element, and the other, the ehe001nc, has no capacitive storage element. More sophisticated electronics are available for directly powering sensors and charging specific batteries. Please contact Chris Ludlow (through our contact page) if you would like to learn more.
Energy Harvester Specification Definitions
*Frequency Range - This refers the range in which the energy harvester can be tuned. The upper limit of the range is where the piezo element has no tip mass. The lower limit has a large tip mass.
*Harvesting Bandwidth - This value refers to the frequency range over which the energy harvester will produce at least 50% of its peak power. For example if the harvester was tuned to 100 Hz with a bandwidth of 3 Hz, it would produce 50% of its peak power (at 100 Hz) at 98.5 Hz and 101.5 Hz.
*Power Electronics - The power electronics involve a simple rectification circuit that changes the AC output of the piezo to a variable DC output dependent upon load.
*Enclosure - If a product includes an enclosure it comes with a anodized aluminum enclosure with integrated electronics and power output cable. The clamp is integrated into the enclosure. If a product does NOT come with an enclosure only the piezo pack is included.
