Beschreibung
Zusammenfassung:	A sensing system includes a sensor including a flexible substrate and a graphene oxide sensing element deposited on the flexible substrate. The graphene oxide sensing element has first and second sides. First and second electrical connectors coupled to the first and second sides of the graphene oxide sensing element, respectively. A power source is coupled to the first and second electrical connectors of the sensor and is adapted to apply a constant voltage to the sensor. The sensing system also includes a measurement element measuring a current in the graphene oxide sensing element due to the constant voltage and a calculation element calculating an electrical resistance of the graphene oxide sensing element based on the electrical current and the constant voltage and calculating a condition at a location of the sensor based on a relationship between the electrical resistance and the condition for the graphene oxide sensing element.
