Nuclear Magnetic resonance (NMR) is a well-known spectroscopic technique used by chemists and is especially powerful in detecting the presence of water and distinguishing between arbitrary physisorbed and chemisorbed states. This ability is of particular importance in the search for extra-terrestrial life on planets such as Mars.
This paper discusses the fabrication aspects of a sensor device that is based on a sputter deposited multilayer giant magnetoresistive (GMR) sensor. The device consists of a micromachined microstructure (membrane), GMR sensor, and a sputtered hard magnetic thin film element on to microstructure.
The measurement of acceleration has been accomplished using several technologies in high-reliability applications such as guidance control, detonation, and shock/vibration measurement. Electromechanical, piezoelectric, piezoresistive, and capacitive acceleration sensors are available and the literature pertinent to giant magnetoresistive sensors (GMR) for the above applications are scanty.
