Two-Sensor System for Absolute Age and Temperature History
Technology Summary
Numerous commercial and military applications require knowing the absolute age and/or temperature history of a device or system starting from the time it is assembled or commissioned. Ideally this information could be obtained simply and without power. The Sandia-developed age and temperature history sensor is a physical materials system solution to address this need.Description
Sandia’s passive sensor is based on diffusion of one metal into another, or into a semiconductor, as a function of time and temperature. This new technology leverages two similar sensors with different activation energies, as illustrated in Figure 1 of the attached market sheet. Sensors can be conductive, capacitive, optical, visual or crystalline. Devices can be created using standard metal deposition techniques on common semiconductor and micro-device substrates, including sputter coating, chemical vapor deposition and electrochemical methods.Benefits
Does not require power during the aging period
Can determine absolute age independently of temperature history
Suitable for emplacement on circuit boards
