Abstract
An energy harvesting device may include a pneumatic system inlet configured to receive a pressurized gas; a pneumatic-to-electrical (PN/E) transducer that converts a flow of the pressurized gas into generated electrical energy; and an electrical device coupled to receive the electrical energy of the PN/E transducer.
Claims20
An energy harvesting device, comprising:
- a pneumatic system inlet configured to receive a pressurized gas;
- a flow control device coupled to the pneumatic system inlet, wherein the flow control device is configured to increase a flow velocity of the pressurized gas;
- a pneumatic-to-electrical (PN/E) transducer that converts the flow of the pressurized gas into generated electrical energy;
- and
- an electrical device coupled to receive the electrical energy of the PN/E transducer.
2 more elements
An energy harvesting device, comprising:
- a pneumatic system inlet configured to receive a pressurized gas;
- a chamber coupled with the pneumatic system inlet;
- one or more valves coupled with the at least one chamber, wherein the one or more valves are configured to regulate a flow of the pressurized gas into and out of the chamber;
- a pneumatic-to-electrical (PN/E) transducer comprising a mechanical element configured to move in response to increasing pressure in the chamber, wherein the PN/E transducer is configured to generate electrical energy from the movement of the mechanical element;
- and
- an electrical device coupled to receive the electrical energy of the PN/E transducer.
