Abstract
Disclosed is a sensing device including a guided surface wave receive structure, a physical parameter sensor, and a radio frequency transmitter. The guided surface wave receive structure may be configured to obtain electrical energy from a guided surface wave traveling along a terrestrial medium. The physical parameter sensor may be coupled to the guided surface wave receive structure. The physical parameter sensor may also measure a physical parameter associated with a physical environment local to the physical parameter sensor. The radio frequency transmitter may be coupled to the guided surface wave receive structure and communicatively coupled to the physical parameter sensor. The radio frequency transmitter may also obtain a physical parameter measurement and transmit the physical parameter measurement over a wireless network.
