Research Institution
Hi-Technology, Inc. (Hi-Z) proposes to use thermoelectric devices in developing an alternate method of providing power for wireless sensors. A thermoelctric gneator (TEG) converts heat directly to electicity in a compact, reliable, robust, solid-state module. Hi-Z has developed thermoelectric module technology that is well suited for this Navy application. Using the experience gained in the current Phase II SBIR where a small power-harvesting TEG is being designed and fabricated for Navy wireless sensors, Hi-Z is planning to examine all potential heat sources and select the best one for the conceptual design of a TEG for this application generating 10-100mW constant power and having a minimum life of 4 years. In the Phase II SBIR, Hi-Z is designing a TEG that utilizes the heat transfer between shipboard waste heat sources and the ambient air to generate electricity for wireless sensor. In two prior Navy applications Hi-Z designed TEGs for senors wih the one installed on USS Monterrey (CG61) operating on just a 5C difference between the temperature of the space inside the ship and the ships hull. In order to satisfy the desired small form factor for the alternate power source, Hi-Z proposes to apply its innovative Quantum Well thermoelectric technology that has four times higher conversion efficiency than SOTA bulk thermoelectrics.
