The invention encompasses an electrical apparatus. Such apparatus comprises a first substrate having first circuitry thereon. The first circuitry has a terminal extending therefrom, and the terminal defines a first electrical node. The apparatus further comprises a first dielectric material covering a predominate portion of the first circuitry and not covering the first electrical node. Additionally, the apparatus comprises a second substrate having second circuitry thereon. The second circuitry has a terminal extending therefrom, and such terminal defines a second electrical node. A second dielectric material covers a predominate portion of the second circuitry, but does not cover the second electrical node. The second substrate comprises a different material than the first substrate. A portion of the second substrate is over a portion of the first substrate to define an overlap between the first and second substrates. The second electrical node overlaps the first electrical node in the overlap between the first and second substrates. A conductive material is within the overlap between the first and second substrates and electrically bonds the first and second electrical nodes to one another. The invention also encompasses termite sensing devices, methods of forming electrical apparatuses, and methods of sensing termites.
