An increase of miniature electronic devices as well as the inherent power limitations possessed by batteries presents the need to develop a potentially more efficient power source. A liquid, pre-mixed micro combustion device made from Low Temperature Co-Fired Ceramics (LTCC) has been developed at Boise State University. This simple and robust design uses an embedded circuit and combustion chamber to combust a mixture of hydrogen gas and air. The combustion chamber design is of specific importance as the flame must stabilize in order to provide enough heat to extract for power generation. Using the standard fabrication process for LTCC three device prototypes were developed in which the combustion chamber geometries varied. These three generations of devices will be tested over a range of equivalence ratios and flow rates to determine the most efficient design. A non-destructive analysis of substrate temperature during combustion will be made through the implementation of forward looking infrared (FLIR) imagery. The results from this investigation will be documented. Several conclusions will be presented to improve the ability to use LTCC in high temperature combustion applications.
