| Outline of Final Research Achievements |
In this study, to monitor two kinds of information which are water content unaffected by ion concentration and ion concentration unaffected by water content, new measurement methods of them were established. A sensor chip to monitor them was fabricated.
Information of phases and amplitudes of impedance characteristics were proved that the water content and ion concentration can be measured by the information, using electrical models of soil. The sensor chip integrated with phase sensing area and electric conductivity sensing area was fabricated by Si-LSI process. The sensor performed to detect the ion concentration unaffected water content. I was successfully fabricated the water content and the ion concentration sensor chip for precision agriculture and disaster prevention fields.
