the bottom portion comprises a second strap configured to be worn proximate to a groin area of the wearer; and
at least one of the first strap and the second strap comprise a cooling component and a heating component.
2. The wearable personal thermal management system of claim 1 , wherein the at least one of the first strap and the second strap comprise a phase change material configured to absorbs thermal energy when an ambient temperature exceeds a predetermined threshold and/or releases thermal energy when the ambient temperature falls below a second predetermined temperature threshold.
3. The wearable personal thermal management system of claim 1 , wherein the thermally sensitive area is proximate to one or more of the following areas: a carotid artery area, an axilla area, a groin area, an arm area, a back area, a chest area, an abdominal area, a leg area, a foot area, and a head area.
4. The wearable personal thermal management system of claim 1 , wherein the cooling component comprises a pulse pump configured to circulate a coolant.
5. The wearable personal thermal management system of claim 1 , further comprising a computing device communicatively coupled to control the cooling component and/or the heating component.
6. The wearable personal thermal management system of claim 1 , wherein the heating component comprises a composition comprising graphene sheets and a polymer.
7. The wearable personal thermal management system of claim 1 , wherein the heating component comprises one or more of a thermally conductive adhesive, a thermally conductive gasket, and a thermally conductive seal.
8. The wearable personal thermal management system of claim 1 , wherein at least one of the first strap and the second strap comprises a fluid conduit configured to circulate a coolant.
9. The wearable personal thermal management system of claim 1 , wherein the cooling component utilizes a coolant comprising a coefficient of performance of 0.30 harness.
10. The wearable personal thermal management system of claim 1 , wherein the harness is formed in a manner to be selectively removable from a garment.
11. The wearable personal thermal management system of claim 2 , wherein the phase change material comprises at least one of a hydrated inorganic salt, a linear long chain hydrocarbon, polyethylene glycol, a fatty acid, a stearate, a metal, a carbon nanofibers, paraffin, a wax, a plastic crystal, a eutectic composition, an eicosane, nonadecane, octadecane, heptadecane, hexadecane, 2,2-dimethyl-1,3-propanediol, 2-hydroxymethyl-2-methyl-1,3-propanediol, and polyethylene glycol.
12. The wearable personal thermal management system of claim 1 , wherein the harness comprises a computing device that controls the cooling component and/or the heating component.
13. The wearable personal thermal management system of claim 1 , wherein the cooling component and/or the heating component are wirelessly controlled by a computing device.
14. The wearable personal thermal management system of claim 1 , wherein the cooling component utilizes one or more of a nanofluid, a thermofluid, water, R-134a, R-717, propane, butane, R-744, R-22, R-410A, hydrogen, helium, nitrogen, ammonia, and air to provide a cooling effect.
15. The wearable personal thermal management system of claim 1 , wherein the harness is formed in a manner to be permanently included a garment.
16. A method for forming a wearable personal thermal management system comprising:
forming a harness comprising an upper portion and a bottom portion;
wherein
the upper portion comprising a first strap configured to be worn proximate to an axillae region of a wearer;
the bottom portion comprising a second strap configured to be worn proximate to the wearer's groin area; and
the first strap and the second strap each comprise a cooling component and a heating component.
17. The method of claim 16 , wherein the at least one of the first strap and the second strap comprises a phase change material configured to absorb thermal energy when an ambient temperature exceeds a first predetermined temperature threshold and/or releases thermal energy when the ambient temperature falls below a second predetermined temperature threshold.
18. The method of claim 16 , wherein the thermally sensitive area is proximate to one or more of the following areas: a carotid artery area, an axilla area, a groin area, an arm area, a back area, a chest area, an abdominal area, a leg area, a foot area, and a head area.
19. The method of claim 16 , further comprising positioning a fluid conduit within at least one of the first strap and the second strap; and wherein fluid conduit is configured to circulate a coolant.
20. The method of claim 16 , wherein the harness is formed in a manner to be selectively removable from a garment or permanently included in the garment.
