Ultrasonic Power Sensory System
Includes a first and a second transducer coupled together through a coupling medium communicating undulating pressure wave for the transfer of electrical power into an undulating pressure wave communicated into an electrical response. This is a signal that can be converted into useful power for an embedded sensory and actuation control unit. The primary advantage is the transfer of power through a coupling medium without the use of electrical power wires.
