A system and method include a non-linear dynamic sensor, such as a magnetic field sensor, having an oscillator with a dynamic response that passes through a critical point beyond which the oscillator responds in an oscillatory regime. A processor operatively connected to the non-linear dynamic sensor is configured to, based upon an input signal x received by the non-linear dynamic sensor, adaptively self-tune the non-linear dynamic sensor to a dynamic range within the oscillatory regime adjacent to the critical point such that the input signal x spans the entire dynamic range. An array of such sensors includes a global feedback capability to mitigate coupling losses.

Non-linear biomimetic magnetic field sensor and array

The dynamics of a nonlinear sensor are configured to mimic threshold crossing dynamics of an integrate-fire neuron with negatively correlated inter-spike intervals. The configuration of the sensor results in a biomimetic sensor that provides results with an accuracy that mimic neuron sensing.

Biomimetic sensor and method for configuring biomimetic sensor

A nonlinear dynamic system comprising: a number N of nonlinear components, wherein each nonlinear component experiences intrinsic oscillation when a coupling parameter &#x3bb; is tuned past a threshold value, and wherein the nonlinear components are unidirectionally coupled together in a ring configuration; and a signal generator configured to generate N coherent locking signals; wherein each locking signal is phase shifted by 2&#x3c0;/N with respect to the other locking signals; and wherein the signal generator is coupled to the nonlinear components such that each locking signal locks a frequency of the intrinsic oscillation of one of the nonlinear components to a frequency of the locking signal.
