Abstract

A system includes a network of a plurality of sensing/control/identification devices distributed throughout a machine, each of the sensing/control/identification devices associated with at least one sub-system component of the machine and operable to communicate through a plurality of electromagnetic signals. Shielding surrounds at least one of the sensing/control/identification devices to contain the electromagnetic signals proximate to the at least one sub-system component. A communication path is integrally formed in a component of the machine to route a portion of the electromagnetic signals through the component and a remote processing unit operable to communicate with the network of the sensing/control/identification devices through the electromagnetic signals, wherein at least a portion of the sensing/control/identification devices comprise a wide band gap semiconductor device and wherein at least a portion of the sensing/control/identification devices comprise an on-chip antenna.
