  We associate tape casting and magnetron sputtering techniques to engineer
flexible nanostructures using ZrO$_2$ green tape as substrate. We
systematically investigate the structural, magnetic and electrical properties
of NiFe/Cr/NiFe trilayer nanostructures, with variable thickness values of the
NiFe and Cr layers, grown onto rigid glass and flexible ZrO$_2$ tape
substrates. We verify the mirroring of these properties in the trilayer
nanostructures, irrespective on the kind of employed substrate. The fact that
the trilayer nanostructures can be reproduced in distinct substrates
corresponds to an important advance for their applicability. The results place
the ZnO$_2$ green tape as an attractive candidate for application as low-cost
flexible substrate in the development of electrical and magnetic sensor
elements with high sensitivity to mechanic stress.
