A thermal management system for an embedded environment is described. The thermal management system includes a pleumo-jet that has at least one wall defining a chamber, at least one piezoelectric device on the at least one wall, and a compliant material within the at least one wall and encompassing the chamber. The compliant material has at least one opening providing fluid communication between said chamber and the embedded environment. A cooling system is also described. A method for making a pleumo-jet is also described.

1. A thermal management system for a heated environment, comprising: a pleumo-jet, comprising: a first wall;a second wall;an at least one active material on at least one of said first and second walls; anda spacer element formed of a compliant material and positioned between said first and second walls so as to be sandwiched therebetween, the spacer element configured to space the first wall apart from the second wall such that the spacer element together with the first and second walls define and encompass a chamber, said spacer element having at least one opening facilitating fluid communication between said chamber and the heated environment. 2. The thermal management system of claim 1, wherein said compliant material comprises an elastomeric material. 3. The thermal management system of claim 1, comprising an electrical circuit to provide an electrical current to said pleumo-jet. 4. The thermal management system of claim 3, wherein said electrical current comprises a sine wave. 5. The thermal management system of claim 1, wherein the heated environment includes single board computers, programmable logic controllers (PLCs), operator interface computers, laptop computers, cell phones, personal digital assistants (PDAs), and personal pocket computers. 6. The thermal management system of claim 1, wherein the heated environment comprises at least one heated body. 7. The thermal management system of claim 6, wherein said at least one opening is positioned to eject an ambient fluid directly on said at least one heated body. 8. The thermal management system of claim 7, wherein said at least one opening is at an angle transverse to an upper surface of the at least one heated body. 9. The thermal management system of claim 1, wherein said at least one opening comprises a plurality of openings facilitating fluid communication between said chamber and the heated environment. 10. The thermal management system of claim 1, wherein each of said first and second walls is formed of a flexible material configured to flex responsive to activation of said at least one active material, and wherein each of said first and second walls is formed from a single, continuous piece of flexible material. 11. The thermal management system of claim 1, wherein each of said first and second walls has a rectangular profile. 12. The thermal management system of claim 1, comprising: a base upon which said pleumo-jet is positioned; anda plurality of fins surrounding said pleumo-jet. 13. The thermal management system of claim 12, further comprising a plurality of additional pleumo-jets positioned on said pleumo-jet and said base in a stacked arrangement; and wherein each of said plurality of additional pleumo-jets comprises:an additional first wall;an additional second;an additional active material on at least one of said additional first and second walls; andan additional spacer element formed of the compliant material positioned between said additional first and second walls so as to be sandwiched therebetween, the spacer element configured to space the additional first wall apart from second wall such that the spacer element together with the additional first and second walls define and encompass an additional chamber, said additional spacer element having at least one additional opening facilitating fluid communication between said additional chamber and the heated environment. 14. The thermal management system of claim 1, wherein the at least one active material is positioned on each of said first and second walls. 15. A pleumo-jet, comprising: a first flexible wall;a second flexible wall spaced apart from the first flexible wall;an at least one active material positioned on at least one of said first and second flexible walls; anda compliant material connecting said first and second flexible walls and being formed along a perimeter of the first and second flexible walls so as to form a chamber along with the first and second walls, wherein said compliant material comprises at least one orifice for facilitating fluid communication between said chamber and an ambient environment. 16. The pleumo-jet of claim 15, comprising an electrical circuit to provide an electrical current to the at least one active material. 17. The pleumo-jet of claim 15, wherein said compliant material comprises an elastomeric material. 18. The pleumo-jet of claim 15, wherein said pleumo-jet is no larger than meso-scale sized. 19. The pleumo-jet of claim 15, wherein said at least one active material comprises a piezoceramic material. 20. The pleumo-jet of claim 15, wherein said at least one active material is positioned on both of said first and second flexible walls. 21. A method for making a pleumo-jet, comprising: providing a pair of planar flexible walls, at least one of the planar flexible walls having an attached active material;attaching a compliant material between the pair of planar flexible walls such that the compliant material is sandwiched between the pair of planar flexible walls, said compliant material having at least one orifice; andadding electrical contacts to the pair of planar flexible walls. 22. The method of claim 21, wherein said providing comprises providing said attached active material for each of the pair of planar flexible walls. 23. The method of claim 21, wherein said attaching comprises attaching the compliant material having an elastomeric material between the pair of planar flexible walls. 24. The method of claim 21, wherein said attaching comprises: dispensing the compliant material as a semi-liquid silicone-based material along a perimeter area of one of the planar flexible walls; andplacing another of the planar flexible wall in contact with the semi-liquid silicone-based material; and drying the semi-liquid silicone-based material. 25. The method of claim 21, wherein said attaching comprises: forming the compliant material from a pre-made sheet of silicone-based material; andbonding the compliant material to each of the pair of planar flexible walls. 26. The method of claim 21, wherein said pair of planar flexible walls comprises a pair of rectangular walls.
