Abstract
Aspects of this disclosure relate to one or more particles that move within a container in response to a magnetic field. A measurement circuit is configured to output an indication of the magnetic field based on position of the one or more particles.
Claims24
A system for magnetic field measurement, the system comprising:
- a container comprising an integrated structure;
- at least one particle within the container, wherein the at least one particle moves within the container in response to a magnetic field, wherein the system is unpowered during exposure to the magnetic field;
- and
- a measurement circuit configured to receive an input signal associated with the magnetic field from the integrated structure and to output an indication of the magnetic field.
A system for magnetic field measurement, the system comprising:
- a container comprising a conductive structure that provides a connection from within the container to external to the container;
- at least one particle within the container, wherein the at least one particle moves within the container in response to a magnetic field;
- and
- a measurement circuit configured to receive an input signal associated with the magnetic field by way of at least the conductive structure and to output an indication of the magnetic field.
A system for magnetic field measurement, the system comprising:
- a container comprising an integrated structure;
- at least one particle within the container, wherein the at least one particle moves within the container in response to a magnetic field;
- a measurement circuit configured to receive an input signal associated with the magnetic field from the integrated structure and to output an indication of the magnetic field;
- and
- an antenna configured to wirelessly transmit information associated with the magnetic field.
A method of magnetic field measurement, the method comprising:
- taking a measurement of a system using a detector while the detector is powered, wherein the system comprises a container and at least one particle, and wherein the at least one particle moves within the container in response to a magnetic field while no power is applied to the detector;
- outputting an indication of the magnetic field based on the measurement;
- and
- resetting a position of the at least one particle.
