A disposable electronic device has a body constructed of juxtaposed lengths of an elongate, ribbon-like substrate of dielectric material secured together to establish a multiple-layered self-sustaining structure, and circuitry formed on the substrate. At least a portion of the circuitry is constructed of a deconstructable material which is deconstructed to render the device inoperative by at least one of the following: interrupting a securement of juxtaposed lengths of the substrate, exposing the deconstructable material to at least one of ambient conditions including ambient air, ambient light and ambient moisture, and reaching a predetermined accumulated amount of time during which the circuitry is operated. At least a portion of the substrate is constructed of deconstructable material which is deconstructed by exposure to at least one of the ambient conditions to render the device ready for disposal.
