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 …

Acoustic energy transfer (AET) technology has drawn significant industrial attention recently.
This paper presents the reviews of the existing AETs sequentially, preferably, from the early …

When a sensor is located within a metallic housing, conveying data back to a controller or
data logger is not trivial. To maintain structural integrity, or simply for ease of installation, it is …

This paper presents a method for two-way ultrasonic communication and power delivery
through thick metallic enclosures without physical penetration. Acousticelectric channels are …

Thick metal barriers prevent the use of conventional electromagnetic wireless power transfer
due to Faraday shielding effects. Here, for the first time, we demonstrate power transfer to …

Piezoelectric acoustic-electric power feed-through devices transfer electric power wirelessly
through a solid wall using elastic waves. This approach allows for the elimination of the …

Ultrasonic wireless power transfer (UWPT) has been a promising technology to recharge the
sensor batteries that locate in enclosed metal containers. An accurate and comprehensive …

Ultrasonic guided plate waves (Lamb waves) can be used to transfer power along the length
of metal plates, achieving longer distance wireless power transfer (WPT), while not being …

A coupled of ultrasonic transducer can act as a power transmission device by means of
Acoustic Energy Transfer (AET). This method is relatively new method of contactless energy …

A system to wirelessly convey electric energy through a thin metal wall is proposed in the
paper, where 2 piezoelectric transducers are used to realize energy transformation between …
