Sensor with electrically conductive sensing element

A temperature sensor, comprising:

• a first electrical terminal;
• a second electrical terminal;
• and
• a self-passivating sensing element coupled between the first electrical terminal and the second electrical terminal and configured to allow an electric current to flow through the self-passivating sensing element from the first electrical terminal to the second electrical terminal,
• wherein an electrical property of the self-passivating sensing element varies based on at least one of:
• a temperature of:
• an environment in which the temperature sensor is positioned,
• or
• a specimen to which the temperature sensor is coupled.

A strain sensor, comprising:

• a first electrical terminal;
• a second electrical terminal;
• and
• a self-passivating sensing element coupled between the first electrical terminal and the second electrical terminal and configured to allow an electric current to flow through the self-passivating sensing element from the first electrical terminal to the second electrical terminal,
• wherein an electrical property of the self-passivating sensing element varies based on a strain experienced by a specimen to which the strain sensor is coupled.
