The electronic devices are getting smaller and smaller in present days. Many big corporate have been invested in the electronics’ R&D, so that they can invent and develop tiniest electronic components.

In this case, there’s a group of researchers from Purdue University have developed a new class of tiny mechanical devices.

Based on the reports, even though the device is so tiny, but it containing vibrating, hair-thin structures, which is could be used to filter electronic signals in cell phones or other electronic devices!

Tiny 'MEMS' Devices

The research team named the devices as, “The resonators”. They can vibrate in specific patterns, cancel out signals and allows other to pass through it. Honestly, it’s a new type of “band-pass” filter, which is always being used in electronic to allow some signals to pass through a cell phone’s circuitry, but blocking other unwanted signals in the same time!

Professor Jeffrey Rhoads, an assistant professor of mechanical engineering at Purdue University described that the new tiny ‘MEMS’ devices have giving a new hope to further miniaturize band-pass filters. The device is simply a good example of a microelectromechanical system (MEMS), as it contains many tiny moving parts.

Frankly, the band-pass filter design is giving higher performance than previous MEMS technology. In addition, the new design is functioning better than the traditional linear arrangement as well! [sciencedaily]
