Abstract
Wounds dressings, systems, and methods are presented that involve using a patient's body heat to enhance liquid removal from the wound dressing through a high-moisture-vapor-transmission-rate drape. Additional heat sources or devices, such as nano-antennas or electrical heating elements, may be added or used separately to enhance the removal liquid from the wound dressing. Other dressings, systems, and methods are presented herein.

A system comprising:
- a manifold configured to be disposed adjacent to a tissue site;
- a first interface configured to be disposed adjacent to the manifold, the first interface being fluid permeable and further configured to harvest thermal energy from the tissue site;
- a processor disposed adjacent of the first interface, the processor configured to receive and store liquid;
- a second interface disposed adjacent to the processor and coupled to the first interface to receive the thermal energy harvested from the tissue site, wherein the second interface is configured to enhance the vapor transmission from the processor using the thermal energy harvested, the second interface being fluid permeable;
- a drape configured to be disposed over the second interface wherein the drape is configured to directly contact the second interface in a region of the second interface where the processor is between the first interface and the second interface;
- and
- a reduced-pressure source fluidly coupled to the manifold.
