Abstract
A physiological feature of a subject is monitored by implanting a plurality of targets, such as magnets, and detecting at least one change in a physical property of the targets, followed by modifying a physiological feature of the subject in response to a change of state detected by the change in physical property detected in the targets. Cutaneous sensory feedback and proprioceptive feedback in a subject, as well as selective stimulation of axons or nerve fascicles of a neuron of a subject are provided.

A method for detecting a physical property of tissue, comprising:
- implanting targets at an individual tissue;
- employing an array of sensors to detect a magnetic field at each of the sensors of the array;
- estimating a position and orientation of at least two of the targets based on the detected magnetic fields;
- and
- determining at least one state of the at least two targets relative to each other based upon the estimated position and orientation of each of the at least two targets, wherein the state of the targets is indicative of a physical property.
A device for detecting a physical property of tissue, comprising:
- an array of sensors configured to detect a magnetic field from targets at an individual tissue;
- and
- electronics configured to:
- estimate a position and orientation of at least two of the targets based on the detected magnetic fields;
- determine at least one state of the at least two targets relative to each other based upon the estimated position and orientation of each of the at least two targets;
- and
- provide an indication of a physical property of the tissue based on the determined at least one state.
A method for calibrating magnetometers, comprising:
- generating a magnetic field in proximity to the magnetometers;
- processing magnetic field signals generated by the magnetometers based, at least in part, on the magnetic field detected by the magnetometers;
- and
- calibrating at least one of bias, location, or angle of the magnetometers based, at least in part, on the magnetic field signals.
