Abstract
A remote sensing device includes a plurality of components arranged to form a resonant electrical circuit. The plurality of components includes at least one sensing component having sensing elements distributed among regions of an area of interest. The sensing elements are arranged so that a resonant characteristic of the resonant circuit is modifiable by an external event affecting an element associated with a region. The sensing component may be a capacitor having spatially distributed capacitive elements or an inductor having spatially distributed inductive elements.
