The present technology provides a threshold sensing device including an inductor, a ferroelectric varactor, and a resonator sensitive to a selected parameter of interest. The unbiased varactor has a memory window that grows proportionally with the partial switching of the varactor's ferroelectric domains. A DC voltage is generated across the varactor which, above a parameter threshold sensed by the resonator, drives the ferroelectric switching of the varactor. A nonvolatile shift in a radio frequency readout signal serves as a memory of an exceeded parameter threshold detected by the resonator. The sensor device can be used to detect temperature violations in a cold chain or the presence of a chemical or biological agent and is capable of battery-less operation.
