7.12 Nanowire Magnetic Compass and Position Sensor
Peczalski (2010) reported a nanowire magnetic sensor and position sensor for
determining the position of a magnetic object and direction of magnetic eld.
The magnetic compass includes a plurality of magnetic nanosensors printed
on a exible substrate, which covers 360° angle at equal intervals. Each mag-
netic nanosensor generally includes magnetoresistive nanowires with high
magnetic sensitivity printed in sets of 10 on the exible substrate. Individual
nanosensors are connected into resistive bridge conguration using AMR
wires and/or GMR wires. The exible substrat ...
