Sounds Excellent! Vesper Develops a MEMS Microphone with a Difference

The huge popularity of ultra-mobile devices, such as smartphones and tablets, has driven demand for miniaturized electronics, and this has encouraged the use of relatively tiny MEMS (microelectromechanical systems) microphones.


Boston-based Vesper is pioneering a new type of MEMS microphone, a piezoelectric MEMS microphone, as opposed to the more conventional capacitive MEMS microphone. Vesper claims this enables a higher signal-to-noise ratio (SNR), for greatly improved audio quality and sensitivity.

More Fiber in the Diet: Carbon-Fiber Composites See Increasing Demand

Carbon fiber consists of crystalline filaments, merely a few microns in width. But while the filaments are thin, they can impart high strength and rigidity to plastics, and the resulting composites, generically known as carbon-fiber reinforced plastics (CFRP), are in increasing demand across a variety of industries. In aerospace and automotive, for example, fuel-efficiency favors replacing metal parts and components with lighter CFRP counterparts. The Boeing 787 Dreamliner is a well known case in point, where the goal was an aircraft 20% more fuel-efficient than the 767 it was replacing.
