Abstract
Abstract A system includes a first transducer and a second transducer coupled together through a coupling medium communicating input and output undulating pressure waves between the first and second transducers for the transfer of input and output data between an external controller and an embedded sensory and actuating unit. The controller providing input data signals energizing the first transducer and the embedded unit providing output data signals energizing the second transducer collectively for bidirectional communication of data between the controller and embedded unit for functional sensor and actuator process control. The primary advantage of the system is the bidirectional transfer of data through a coupling medium without the use of electrical power wires for controlling embedded sensors and actuators.
