Flexible temperature sensor and sensor array

A method for manufacturing a device, the method comprising:

• providing a substrate;
• depositing a conductive polymer film on the substrate, wherein the conductive polymer film has a resistance that changes with temperature and wherein depositing further comprises:
• controlling a thickness of the conductive polymer film on the substrate, wherein controlling the thickness comprises configuring the thickness to be in a range from about 10 nm to about 150 nm;
• and
• selecting a ratio of the conductive polymer to a dopant used therewith;
• coupling a pair of electrodes to the conductive polymer film, wherein the pair of electrodes are configured to communicate electrical signals to the conductive polymer film;
• and
• operatively coupling a meter to the conductive polymer via the pair of electrodes, wherein the meter is configured to measure the resistance of the conductive polymer film
• wherein the device is configured as a temperature sensor with a sensitivity within the range of about 3 Ω/° C. to about 130 Ω/° C.
