Abstract
Disclosed is a device for moving a liquid in a substantially loss-free operation, the device made of at least a photothermal film; a pyroelectric crystal over the photothermal film; and a superomniphobic surface over the pyroelectric crystal, wherein the device is configured to move the liquid in the substantially loss-free operation with a beam of light.
Claims15
A device for moving a liquid in a substantially loss-free operation, comprising:
- a tri-layered substrate, further comprising:
- a photothermal film;
- a pyroelectric crystal located on an upper surface of the photothermal film;
- and
- a superomniphobic surface located on an upper surface of the pyroelectric crystal,
- wherein the device is configured to move the liquid over the superomniphobic surface in the substantially loss-free operation with a beam of light.
3 more elements
An apparatus for moving a liquid in a substantially loss-free operation, comprising:
- a tri-layered substrate, further comprising:
- a photothermal film base layer;
- a pyroelectric crystal located on an upper surface of the photothermal film;
- and
- a superomniphobic surface located on an upper surface of the pyroelectric crystal, the superomniphobic surface configured to interface with the liquid;
- and
- a light generation component configured to irradiate a beam of light onto the superomniphobic surface.
4 more elements
A method of transporting a liquid in a substantially loss-free manner, comprising:
- irradiating a beam of light onto an upper surface of a superomniphobic layer, wherein the superomniphobic layer is located on a pyroelectric crystal, and the pyroelectric crystal is further located on a photothermal film, whereby the liquid is present on the upper surface of the superomniphobic layer not in contact with the pyroelectric crystal.
