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 …

This paper presents a system capable of simultaneous high-power and high-data-rate
transmission through solid metal barriers using ultrasound. By coaxially aligning a pair of …

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 …

Acoustic-electric channels have been used in the recent past to send power and data
through thin metallic barriers. Acoustic-electric channels formed along a structure which are …

Backscatter communication enables miniature, batteryless, and low-cost wireless sensors.
Since electromagnetic waves are strongly attenuated in several scenarios, backscatter …

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

In many commercial, industrial, and military applications, supplying power to electronics
through a thick metallic barrier without compromising its structural integrity would provide …

This paper presents a novel system capable of simultaneous high-power and high data-rate
transmission through solid metal barriers using ultrasound. By co-axially aligning a pair of …

A link-adaptive frequency division multiplexing (OFDM) ultrasonic physical layer is proposed
for high-datarate communications through metal walls. The ultrasonic link allows for …

The linear propagation of electromagnetic and dilatational waves through a sandwiched
plate piezoelectric transformer (SPPT)-based acoustic-electric transmission channel is …
