2B3UM, abbreviated from “two-beam-three-electrode-ultrasonic-measurement”, is a versatile sensing technology used to measure the physical parameters of acoustic-wave propagation in fluids and solids. With such measurements, researchers and engineers are able to identify and analyze various types of acoustic waves, such as sound and ultrasound. In addition, the technology is also used to detect potential oil and gas deposits. In recent years, 2B3UM has shown promise in the field of biomedical engineering, where it can be used to identify anomalies and potential diseases in tissues. In this article, we will discuss the application field and working principle of 2B3UM.

2B3UM is a contactless, non-invasive technique that does not require direct contact with the surface of the sample. This makes it an invaluable tool in biomedical applications, where tissue samples must not be damaged. In addition, the technology can be used to detect and analyze acoustic waves generated in solids, liquids, and gases. This makes it useful in a variety of scientific and engineering applications, including but not limited to acoustic materials characterization, seismic surveying, oil and gas exploration, underwater communications, monitoring of food freshness, and industrial process control.

The 2B3UM technique is based on the principle of backscattering in a signal. By directing two beams of ultrasound at a sample, two echoes of the signal are produced that are 90 degrees out of phase with each other. By analyzing these two echoes, researchers and engineers can identify the acoustic properties of the sample, such as speed of sound and attenuation. Furthermore, they can also identify anomalies, such as air bubbles, voids, and fractures, and localize them in the sample.

To accomplish this task, researchers and engineers require two transducers that are configured in a three-electrode configuration. The three electrodes are arranged such that the first two act as the transmitter and receiver of the signal, while the third acts as a reference. As the two beams of ultrasound impinge on the sample, they cause the medium to vibrate, creating an acoustic wave that is visible as a waveform on an oscilloscope. By analyzing the waveform, researchers and engineers can identify a variety of features, such as signal strength, phase, amplitude, frequency, and damping.

In addition to biomedical applications, the 2B3UM technique has been used in a variety of other applications, such as non-destructive testing of materials, nuclear safety monitoring, and aerospace engineering. It has also been used to detect early stages of corrosion in subsea pipelines. In geophysics, the technique has been used to map the properties of subsurfaces, allowing researchers to track the flow of energy and fluids, and to detect potential oil and gas deposits.

In summary, 2B3UM is a versatile and powerful tool that has a multitude of applications in various sciences and engineering fields. By using two beams of ultrasound and three electrodes, researchers and engineers are able to detect and analyze acoustic properties of samples ranging from solids to gases. This makes the technology an invaluable tool for researchers and engineers, and its use is only expected to expand in the coming years.
