Original Abstract Submitted
A sensing device is provided. For example, a sensing device may include a conducting element, a DC voltage source, a voltage measuring device, a first switching circuitry to selectively connect the DC voltage source to the conducting element, and a processor that controls the first switching circuitry. The conducting element comprises first and second dissimilar materials arranged such that there is a first junction between the dissimilar materials and a second junction between the dissimilar materials. The processor controls the first switching circuitry to connect the DC voltage source to the conducting element to apply a DC voltage for a first period of time and to disconnect the DC voltage source to measure a voltage over a second period of time.
