In printed electronics, the use of low environmental-impact materials such as conductive carbon black (CB), instead of metals like silver or copper, is expected to enhance the sustainability of the electronics industry. In a conventional passive matrix sensor array, however, accurate measurement of sensor resistance values is hindered by the influence of CB wire resistance. In this study, we proposed and applied a method to compute the true sensor resistance values. Then a temperature sensor array composed of CB wires was demonstrated by using above method.
