“…Later some other articles published by the same research group mainly focused on energy transmission through a cylindrical metal shell [2,3], energy trapping characteristics [4,5], connecting with energy harvesting circuit [6], and nonlinear behavior during the ultrasonic power transmission process [7]. All of them are based on the wave propagation equation and piezoelectric theory.…”

The investigation of the wireless ultrasonic energy and signal transmission through metal barrier into hermitical metallic structures has become an interesting field of research. The most often constructed acoustic-electric ultrasonic power transmission channels are based on piezoelectric transducers. Effective modeling methods with accuracy are essential to the performance prediction and optimal design of such channels. Up to now, there exists a variety of modeling methods including theoretical analytical method, equivalent circuit method, two-port network method, and finite element modeling method. However there is a little chaos about how to choose an appropriate modeling method among them. There is also a lack of a systematic modeling framework presented involving principles, advantages, disadvantages, and constraint conditions of these methods. In this review, a common modeling framework for through-metal-wall acoustic-electric channels based on piezoelectric transducers is presented. The principles of the major modeling methods are introduced and the adoptability and constraints of each method are discussed. For each modeling method, simulation and or experimental results are also presented to validate the accuracy of the corresponding modeling method.

“…These previous work were followed by several papers focusing on physical and mathematical modeling of piezoelectric transducer-based power delivery through metal walls of different geometric shapes with different vibration modes. In [ 36 , 37 , 38 ] the modeling of three-layered cylindrical shell PT configurations are presented, where a pair of cylindrical PZTs are aligned concentrically on the inside and outside of a cylinder of elastic material. These transducers are acoustically coupled to the elastic layer’s inner and outer surfaces operation in the thickness-twist mode of vibrations [ 36 ], thickness-shear mode of vibrations [ 37 ], and thickness-stretch mode of vibrations [ 38 ], respectively.…”

The aim of this review was to assess the current viable technologies for wireless power delivery and data transmission through metal barriers. Using such technologies sensors enclosed in hermetical metal containers can be powered and communicate through exterior power sources without penetration of the metal wall for wire feed-throughs. In this review, we first discuss the significant and essential requirements for through-metal-wall power delivery and data transmission and then we: (1) describe three electromagnetic coupling based techniques reported in the literature, which include inductive coupling, capacitive coupling, and magnetic resonance coupling; (2) present a detailed review of wireless ultrasonic through-metal-wall power delivery and/or data transmission methods; (3) compare various ultrasonic through-metal-wall systems in modeling, transducer configuration and communication mode with sensors; (4) summarize the characteristics of electromagnetic-based and ultrasound-based systems, evaluate the challenges and development trends. We conclude that electromagnetic coupling methods are suitable for through thin non-ferromagnetic metal wall power delivery and data transmission at a relatively low data rate; piezoelectric transducer-based ultrasonic systems are particularly advantageous in achieving high power transfer efficiency and high data rates; the combination of more than one single technique may provide a more practical and reliable solution for long term operation.

“…A significant amount of modeling of such systems has been done using a coupled continuum equation approach. Both planar [9] and cylindrical [10,11] configurations of channels were considered, as well as nonlinear effects [12]. While these models are well developed, they are inherently coupled and therefore channels with many layers are bulky to construct and evaluate.…”
