Abstract
Embodiments of the present disclosure relate to the field of medical instrument, in particular to a sensor device applied in an articulation and an artificial limb system to improve control precision of the sensor. The sensor device of the present disclosure includes a plurality of magnets spaced apart from each other, the adjacent magnets having opposite polarities in a moving direction of the articulation; and at least one magnetic inductor for monitoring a displacement of the magnets caused by movement of the articulation.
Claims13
A sensor device configured to be applied in an articulation, the sensor device comprising:
- a plurality of magnets spaced apart from each other, adjacent magnets of the plurality of magnets having opposite polarities in a moving direction of the articulation;
- and
- at least one magnetic inductor for monitoring displacement of the magnets caused by movement of the articulation, wherein the at least one magnetic inductor is configured to detect magnetic fields of different directions and determine positions of the plurality of magnets based on a number of changes of the magnetic fields when the plurality of magnets move.
