Know Which One Is The World’s Smallest Acoustic Amplifier

Modern cell phones are stuffed with radios to receive and send text messages, phone calls, and high-speed data. These factors depend on the number of radios that are present in the device. The more the radio, the more useful it is. Most radio components, along with amplifiers, are electronic. With acoustic devices, they can be made smaller and better as well. This implies that they would use sound waves in place of electronic radio signals. In this article, we will discuss the world’s smallest acoustic amplifier by Sandia Labs. 

Dr. Lisa Hackett, who is a researcher at Sandia National Laboratories said,

“Acoustic wave devices are inherently compact because the wavelengths of sound at these frequencies are so small — smaller than the diameter of human hair.”

He further added,

“But until now, using sound waves has been impossible for many of these components.”

The 276-MHz amplifier was made with semiconductor materials that consist of 83 layers of atoms thick which is 1,000 times thinner than a human hair by the researchers. 

Inserting an ultrathin semiconducting layer onto a different acoustic device took a delicate process of growing crystals above other crystals, combining them to yet other crystals, and then removing 99.99% of the materials chemically to provide a perfectly smooth contact surface.

The micro amplifier is more than 10 times as efficient as the previous versions. It can raise signal strength by a factor of 100 in 0.2 mm (0.008 inches) having only 36 volts of electricity and 20 milliwatts of power.

The scientists also formulated the first acoustic circulator, which is another important radio component that segregates received and transmitted signals.

Dr. Matt Eichenfield, who is also from Sandia National Laboratories asserted, 

“Together, the petite parts represent an essentially uncharted path toward making all technologies that send and receive information with radio waves smaller and more sophisticated. We are the first to show that it’s practical to make the functions that are normally being done in the electronic domain in the acoustic domain.”
