A four point probe-based resistivity meter using LOG112 and C8051F006 SoCs has been developed. The resistivity meter was calibrated and examined. Current-voltage characteristic-based resistances of resistors are consistent with those labeled to the resistors. Resistivities of the resistors are independent of the injected current, which agree with theory. The resistivity of TiO2 thin film depends on the injected current due to minority and/or majority carrier injection.
