Research Abstract	In this research, a novel sensing mechanism of micro-patterns is proposed using densely arrayed micro heater elements. The purpose of this research is not in the reform of existing technology but to resolve the conventional problems in existing technology fundamentally, so that to realize micro and high security fingerprint sensor device for the personal authentication and identification. The fabrication process technology was developed and the proposed sensing mechanism of micro-patterns was demonstrated through analysis and experimental research.
