Outline of Final Research Achievements |
In this research, we designed and fabricated an identification sensor capable of detecting patterns made of magnetic and conductive inks and examined the possibility of reading fine patterns. As a result, the following results were obtained. It was found that conductive and magnetic pattern can be detected and distinguished by recognizing both amplitude and phase of ECT signal. We modeled the conductive ink and confirmed the agreement between the output predicted by simulation and the experiment result We showed that improving the magnetic circuit by using the magnet improves the sensitivity.
