Magnetoresitive thick film sensors

Research of the development of thick film magnetoresistive sensors is only just ininiated; Ni-based air-fireable pastes developed for non.sensing applications have been studied for the characterization of magnetoresistive responses and new systems are under development aimed at improving the magnetoresitive performance of these materials particularly in terms of magnetoresistive anysotropy and temperature sensitivity. The very promising results of these investigations are reviewed, basic and technological features of thick-film and thin-film ferromagnetic materials are compared and emerging applications of thick film magnetoresistors are delineated.
