Abstract :
Low-density tantalum thin films, several-hundred angstroms thick, sputtered at 1500 V can exhibit relatively stable strain-gauge factors of the order ten, after heat treatment at 150 to 200°C. Temperature compensation can be obtained by means of a bridge network energised with a current source.
