A method of detecting temperature of an electrical terminal. The method includes: applying a material patch to a surface of the electrical terminal, the material patch containing a polymer matrix with a polymeric positive temperature coefficient material which contains a mixture of electrically conductive magnetic particles, whereby the material patch does not appreciably increase the electrical resistance or thermal capacitance of the electrical terminal; and remotely sensing a change in the material patch with an electrically isolated circuit which is external to the electrical terminal to determine if the electrical terminal is operating at a safe temperature to optimize current flow across the electrical terminal.
