Abstract
A system for supplying voltage to a downhole component is disclosed. The system includes: a pyroelectric material disposed in electrical communication with the component, the component configured to be disposed within a borehole in an earth formation; and a heating unit in operable communication with the pyroelectric material and configured to change a temperature of the pyroelectric material and cause the pyroelectric material to generate a voltage to activate the component. A method of supplying voltage to a downhole component is also disclosed.
Claims20
A system for supplying voltage to a downhole component, the system comprising:
- a pyroelectric material disposed in electrical communication with the component, the component configured to be disposed within a borehole in an earth formation;
- and
- a heating unit in operable communication with the pyroelectric material and configured to change a temperature of the pyroelectric material and cause the pyroelectric material to generate a voltage to activate the component.
The system of claim 10, wherein the thin film of pyroelectric material is mounted on a plurality of protrusions extending from the substrate.
A method of supplying voltage to a downhole component, the method comprising:
- disposing the component and a pyroelectric material in a borehole in an earth formation, the pyroelectric material disposed in electrical communication with the component;
- applying thermal energy to the pyroelectric material to cause the pyroelectric material to change temperature and emit a voltage;
- and
- conveying the voltage to the component to activate the component.
