The effects of preheating and prestraining, which are the methods of improving the strain sensitivity of foil gauges, on grain nucleation and grain growth were inspected in detail. Based on the test results, applying stress measurement method which takes notice of grain growth threshold to such treated copper foils, the possibility of far more sensitive stress measurement was examined. Preheating completes grain nucleation and prestraining accelerates grain growth respectively. Due to such treatments to copper foil, and with the value of grain growth threshold being lowered, high precise stress measurement can be done under much lower stress amplitude compared with the conventional electroplating method based on the calibration curve.
