Abstract
A nanowire magnetic sensor and position sensor for determining the position of a magnetic object and direction of magnetic field is disclosed herein. The magnetic compass includes a number of magnetic nanosensor printed on a flexible substrate, which covers 360-degree angle at equal intervals. Each magnetic nanosensor generally includes magneto-resistive nanowires with high magnetic sensitivity printed in sets e.g. of ten on the flexible substrate. The flexible substrate can also be bent to form a circular configuration to detect the azimuth direction of the magnetic field. The individual nanosensors can be connected into resistive Wheatstone bridge configurations by metalization. The magnetic nanosensors can be utilized as a position sensor of a magnetic object for position determination. Additional electronics can also be mounted or printed on the flexible substrate from other type of nanowires.
