| dc.description.abstract | This research proposes a Lorentz force based capacitive magnetic sensor.
The sensor’s mechanical structure and circuit was implemented using the
standard UMC 0.18 m 1P6M CMOS process. The Lorentz force generated by
the excitation current and magnetic field would change the gap between the
sensing electrodes so that we could measure the magnetic field by the readout
circuit. By integrating two different capacitance structures, this design could
respectively sense out-of-plane and in-plane motion so that we could measure
three-axis magnetic field. Finally, we could take this sensor as a current sensor by
measuring the magnetic field generated from the current. | en_US |
