Research abstract

THE PYROELECTRIC ONVERTER IS A FORM OF HEAT ENGINE THAT TRANSFORMS HEAT ENERGY DIRECTLY INTO ELECTRICAL ENERGY. THEPYROELECTRIC CONVERTER HAS THE POTENTIAL FOR LOW OPERATING AND MAINTENANCE REQUIREMENTS. HIGH RELIABILITY AND LIFETIMEARE ATTAINABLE FOR THIS DEVICE BECAUSE THE PYROELECTRIC CONVERTER DOES NOT REQUIRE ANY SOLID MOVING PARTS. THE SPECIFIC TECHNICAL PROBLEM ADDRESSED IN THIS PROJECT IS THATOF MODIFYING THE TEMPERATURE RANGE OVER WHICH THE PYROELECTRIC CONVERTER MATERIALS CAN OPERATE EFFECTIVELY. POLYMERIC MATERIALS WILL BE IRRADIATED TO PRODUCE THE DESIRED PROPERTIES, AND THE CHANGES IN ELECTRICAL AND THERMAL PROPERTIES WILL BE CONFIRMED BY MEASUREMENT. ADVANCED PYROELECTRIC CONVERSION DEVICES WILL OPERATE AT ABOUT 30% EFFICIENCY BY INCORPORATING THE MATERIALS DEVELOPED UNDER PHASES I AND II OF THIS PROJECT.
