Abstract
A method of verifying a condition of a single-crystal pressure sensor is provided. The method includes providing a single-crystal pressure sensor that has at least one electrical characteristic that varies with applied pressure being coupled to a first output and a second output. The pressure sensor also has at least one resistive element therein. A current is applied through the resistive element to heat the pressure sensor. At least one output of the pressure sensor is monitored to determine a response of the pressure sensor to current-induced heat. A verification output is provided based on the response.
