Giant Magnetic Resistance sensor array directly on board — •Laila Bondzio, Torben Tappe, and Andreas Hütten — Bielefeld University, Germany

GMR multilayer systems of Py/Cu-bilayers exhibit nearly triangular shaped GMR curves with a high sensitivity, which is desirable for sensor applications. With a grid of multiple sensor elements a two dimensional magnetic landscapes can be mapped as changes in a magnetic field. To organize and contact a large number of sensor elements on a wide spread area of few centimeters it might be useful to sputter the structure directly onto contacts on a circuit board. Although the circuit board is not an ideal substrate, it has been shown that such application is feasible.
