Abstract

The invention encompasses an electrical apparatus. Such apparatus comprises a first substrate having first circuitry supported thereby. The first circuitry defines at least a portion of a radio frequency identification device. At least one first electrical node is supported by the substrate and in electrical connection with the first circuitry. The apparatus further comprises an input device comprising a second substrate and second circuitry on the second substrate. The second circuitry is in electrical communication with at least one second electrical node. Neither of the first nor second electrical nodes is a lead, and the second electrical node is adhered to the first electrical node to electrically connect the input device with the radio frequency identification device. The invention also encompasses a termite-sensing apparatus. Additionally, the invention encompasses methods of forming electrical apparatuses, and methods for sensing termites.
