Description

<p>In this paper, we introduce the development of a sheet-type magnetic sensor system using flexible organic thin-film transistors. Flexible transistors that make up the system circuit utilize a newly developed thin-film polymer insulator technology, which enables 2 V operation of transistors with high device yield. We also demonstrated two-dimensional magnetic field mapping using a developed magnetic sensor system. Besides, we discuss the importance of 1/f noise, which is an essential internal noise in analog circuits for sensor systems. And finally, we introduce the technical development of the world's lowest 1/f noise in flexible organic transistors.</p>
