    • Disclosed herein are example methods, systems, and devices involving electrically-conductive wires, such as standard IC bonding wires, that are configured so as to operate as inertial sensors. One embodiment of the disclosed methods, systems, and devices may take the form of a system that includes a first electrically-conductive wire and a second electrically-conductive wire, where the first wire and the second wire are electromagnetically coupled; and a sensor oscillator, where the sensor oscillator is coupled to the first wire and the second wire, and where the sensor oscillator is configured to output a sensor-oscillator signal that is frequency modulated based on a change in complex impedance between the first wire and the second wire, where the change in complex impedance is due to a displacement of the first wire relative to the second wire.
