Sensitivity equalization in multi-sensor inductive sensing applications

A system comprising:

• a plurality of resistive-inductive-capacitive sensors, each resistive-inductive-capacitive sensor configured to sense a physical pressure that modifies a resonant frequency of such resistive-inductive-capacitive sensor;
• and
• a calibration subsystem configured to perform a calibration comprising:
• comparing the resonant frequency from each of at least two sensors of the plurality of resistive-inductive-capacitive sensors to determine a sensitivity drift of at least one sensor of the plurality of resistive-inductive-capacitive sensors;
• based on the measured characteristics of the at least two sensors and stored reference characteristics for the at least two sensors, calculating a gain correction factor for the at least one sensor;
• based on the gain correction factor for the at least one sensor and an estimated quality factor for the at least one sensor, calculating a normalization factor for the at least one sensor;
• and
• applying the normalization factor to the measured characteristic of the at least one sensor to equalize sensitivity of the plurality of resistive-inductive-capacitive sensors relative to each other.
