MAGNETIC SENSORS PRINTING AND INTEGRATION: DESIGNS, MATERIALS, METHODS, AND PROCESSES

摘要

An additive manufacturing direct writing method of producing a magnetic pattern on a substrate by extruding one or more filaments of a magnetic ink compound through a nozzle at an extrusion speed on to the substrate where there is a relative speed between the nozzle and the target substrate, and curing the plurality of filaments of magnetic ink compound using UV light and/or heat. A unipolar magnetic pattern can be produced by applying a magnetic field strength to the cured magnetic pattern. A bipolar magnetic pattern is produced by folding a unipolar magnetic pattern in half about a fold crease on the substrate, creating a sandwich of alternating magnetic elements between the substrate. The magnetic flux density can be lateral or perpendicular to the substrate. A magnetic position sensor system includes the magnetic pattern and a magnetic sensor.
