One or more computing devices, systems, and/or methods are provided. In an example, a method includes tuning a sensor comprising a first resonator having an effective gain, a second resonator having an effective loss, and a coupling circuit connected between the first resonator and the second resonator at an extrema degeneracy point with a nonlinear response to a force applied to the sensor. At least one of the first resonator, the second resonator, or the coupling circuit comprises a variable capacitor having a capacitance that varies as a function of the force. The method comprises injecting an input signal into one of the first resonator or the second resonator, receiving an output signal from one of the first resonator or the second resonator, and determining a magnitude of a force based on a difference between a first frequency extrema point and a second frequency extrema point in the output signal.
