TECHNICAL ABSTRACT (LIMIT 200 WORDS)
Sigma Technologies proposes to produce a compact, efficient, solid state thermoelectric cooler that is expected to deliver hundreds of milliwatts of cooling power at low temperatures (<150 K). The proposed device fabrication process is based on Sigma?s proprietary Polymer Metal (PML) technology. In Phase I, Sigma intends to design and evaluate the refrigerator material. In Phase II, Sigma will build a complete refrigeration unit for field evaluation
POTENTIAL COMMERCIAL APPLICATIONS (LIMIT 150 WORDS)
At a reasonable cost, portable coolers will grab a huge share in the refrigeration industry market. Sectors that may benefit from this technology include the home appliance, medical, and the food and beverage industries.
POTENTIAL NASA APPLICATIONS (LIMIT 150 WORDS)
The proposed solid state, lightweight, low relative cost crycooler will have a great impact on onboard instrumentation performance and reliability, factors that are critical to mission success
