Description:

(abstract)

Our lab conducted measurements using thermal imaging by slicing a CIC conductor in sections, heating up a strand on one side and detecting the change in temperature on the other side by the thermal camera. To improve the response speed, it was suggested to use thermistor chips, capable of detecting changes in temperature in the form of voltage with little lag. In this paper, an array of thermistors was tested to see the feasibility of the method, and results will be shown.
