Wireless position sensing and normalization of embedded resonant sensors using a resonator array

•An array of four resonators is sufficient to wirelessly determine X, Y, and angular position of a portable reader.•Position prediction is improved by taking multiple readings along a linear, ‘flyby’ path.•A resonant sensor can be embedded with the resonator array as long as the response signal is in a different frequency window.•The resonant array can correct for sensor signal changes caused by positional changes.•Useful when the sensor and reader cannot be fixed in place through the entire monitoring period, such as re-reading embedded sensors.
