Abstract
A device comprises a first layer of a die. The first layer comprises a microchannel. The microchannel is partially filled with a liquid and partially filled with air. The die also comprises a second layer. The second layer of the die seals a top of the microchannel of the first layer.
Claims21
A method comprising:
- etching a microchannel in a first layer of a die;
- sealing the microchannel of the first layer with a second layer of the die, wherein the microchannel sealed by the first layer and the second layer is isolated such that the fluid is trapped within the microchannel;
- and
- filling the microchannel with a fluid, wherein the microchannel causes the fluid to flow through the microchannel responsive to a temperature gradient created along the microchannel.

A device comprising:
- a first layer of a die, the first layer comprising a microchannel filled with a fluid, wherein the microchannel causes the fluid to flow through the microchannel responsive to a temperature gradient created along the microchannel;
- and
- a second layer of the die, wherein the second layer seals a top of the microchannel of the first layer, wherein the microchannel sealed by the second layer is isolated such that the fluid is trapped within the microchannel.
A device comprising:
- a first layer of a die, the first layer comprising a microchannel, wherein the microchannel is partially filled with a liquid and partially filled with air that creates a meniscus within the microchannel, and wherein the microchannel causes the meniscus to flow through the microchannel responsive to a temperature gradient created along the microchannel;
- and
- a second layer of the die bonded to the first layer, wherein the second layer bonded to the first layer prevents the liquid and the air fluid from moving out of and into the microchannel.
