Multi-stage sensing/control/identification device having protected communication and remote power

A system for a gas turbine engine, the system comprising:

• a component;
• a hardware device operably connected to the component and configured to measure a characteristic of the component;
• an electromagnetic (EM) transmitting source located remote from the component;
• and
• a sensing/control/identification device configured on or proximate to the component, wherein the sensing/control/identification device includes:
• a first stage including:
• a rectification and power conditioning module configured to receive electromagnetic (EM) transmissions from an EM transmitting source via waveguide confinement and convert said EM transmissions to electrical power;
• a communication interface module configured to receive power from the rectification and power conditioning module and at least one of receive the EM transmissions or transmit EM communications via waveguide confinement;
• and
• a control module configured to receive EM transmission data from the communication interface for processing or preparing the EM communications for transmission from the communication interface module;
• a second stage including:
• a tunable control module configured to process and convert instructions or commands from the control module of the first stage into analog or digital signals and generate and transmit an output signal;
• and
• at least one connection between the first stage and the second stage to enable communication between the first stage and the second stage.
