“…To transmit the sensing measurement of an embedded sensor within the metal structure to a receiver placed outside of the metal structure, ultrasonic waves have been recently investigated as the information carriers [4,6,7]. In the amplitude modulation scheme (also known as on-off keying modulation), the sensing measurement is converted into binary digital form consisting of ones and zeros.…”

With the development of machine embedded sensing, wireless communication through metal structures is becoming a critical issue in manufacturing equipment, process monitoring and control. To address it, this paper presents a multi-carrier ultrasonic communication scheme to achieve high-bit data rate for machine embedded sensing through metal structures. To extract the coded information from ultrasonic signal and denoise the signal, a new signal processing method, named multi-scale enveloping symbolic analysis (MuSEnSA), is also formulated by integrating dual-tree complex wavelet packet transform and symbolic analysis. Dual-tree complex wavelet packet transform (DT-CWPT) is firstly investigated by separating multi-carrier signals under noise contamination, given its properties of shift-invariance and flexible time frequency partitioning. A new envelope extraction and threshold setting strategy for selected wavelet coefficients is then introduced to retrieve the coded digital information by taking advantage of symbolic analysis. Numerical and experimental studies are performed to evaluate the effectiveness of the developed signal processing method for injection molding monitoring.

“…A research group at Drexel University is dedicated to studying high-data-rate ultrasonic data transmission through metal walls using sandwiched plate PT configurations [ 57 , 58 , 59 , 60 , 61 , 62 ]. Though the target of their work of developing an ultrasonic system is not for enclosed sensor data communications but for wirelessly repeating data across the bulkheads separating watertight compartments of naval vessels, these two aspects essentially coincide with each other.…”

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 transmissão de dados por ondas ultrassônicas tem sido objeto de estudo em várias aplicações como, por exemplo, em paredes metálicas [1][2][3][4][5][6][7][8] e em comunicações subaquáticas [9]. Sua aplicação pode ser justificada em ambientes onde o uso de outras formas de transmissão de dados não devem ser utilizadas, seja por questões de segurança do sistema físico ou por inviabilidade técnica, como, por exemplo, em caso de monitoramento de tubulação de gás ou de ambientes com risco de explosão [3].…”

Resumo-Este artigo apresenta os resultados experimentais de transmissão de ondas ultrassônicas por uma barra cilíndrica de aço inox 304 de 1 m de comprimento, utilizando multiplexação Ortogonal Frequency Division Multiplexing (OFDM). O sinal OFDM, modulado em amplitude, excita a barra através de transdutores piezoelétricos com frequência de operação de 500 kHz e largura de banda 150 kHz. Usando modulação em quadratura e equalização zero forcing, obteve-se uma taxa máxima de transmissão de 240 kbps, para uma taxa de erro de 10-3. O multiplexador e o demultiplexador OFDM, o modulador e o demodulador em Amplitude foram implementados em MATLAB.
