Sensor, an electrical component part, a method for determining a temperature or a service life of an electrical component and the use of an intermetallic phase or a phase boundary as a sensor

摘要

It is a sensor (1, 7) for detecting the temperature (t) or of the operating time (t) of an electrical component (3) is specified, which a first metallic material (4, 9) and a second metallic material (5, 10), wherein between the first and second metallic material (4, 5 9, 10) of an intermetallic phase (6) or a phase boundary (12) is formed and wherein the thickness (d) of the intermetallic phase (6) or the position (p) of the phase boundary (12) for determining the temperature (t) or of the operating time (t) serves. Furthermore, a method for the determination of a temperature (t) or an operating time (t) of an electrical component (3), as well as the use of an intermetallic phase (6) or a phase boundary (12) as a sensor (1, 7) is specified.n="26"
