High SNR Microphones Are Transforming Laptops Into All-Round Communication Hubs

By Infineon - 01 Mar, 2023 - Comments: 0

Large portions of the workforce continue to work from home or in hybrid models. Although some organizations are largely getting back to ‘normal’, many people have grown accustomed to meeting online. Without face-to-face meetings in the office, productive and efficient communication relies on good tools, from video conferencing software to computer hardware. Two decades ag... » read more

Manufacturing Bits: Sept. 8

Calibrating a microphone The National Institute of Standards and Technology (NIST) has developed a faster and more accurate way to calibrate a microphone. NIST’s new calibration technique makes use of lasers, a promising technology that could supplant today’s methods. The technology could one day be used to calibrate sensitive microphones in factories, power plants and other settings li... » read more

Power/Performance Bits: Sept. 11

By Jesse Allen - 11 Sep, 2019 - Comments: 0

Thread transistor Researchers at Tufts University developed a thread-based transistor that can be fashioned into simple, all-thread based logic circuits and integrated circuits which could be woven into fabric or worn on the skin, or even surgically implanted. The thread-based transistor (TBT) is made of a linen thread coated with carbon nanotubes, creating a semiconductor surface. Two thin... » read more

How To Build A Better MEMS Microphone

By Chris Welham - 21 Feb, 2018 - Comments: 0

We are seeing a lot of interest in simulating noise, particularly for condenser microphones. With any transducer, noise reduction is always a plus, and with microphones there are two specific applications that need low noise. One is where the microphone is positioned away from the sound source, such as in video calling or when using voice commands with tablet computers. The other is where multi... » read more

Bacteria power wastewater cleanup Researchers at the King Abdullah University of Science and Technology (KAUST) are exploring ways to detoxify warm, salty industrial wastewater while simultaneously generating electricity. They are using bacteria with remarkable properties: the ability to transfer electrons outside their cells (exoelectrogenes) and the capacity to withstand extremes of temperat... » read more

MEMS Microphones: A Bright Spot Among Commoditized Consumer Sensors

By Jun Yan - 16 Mar, 2017 - Comments: 0

MEMS microphones have emerged as a bright spot among consumer sensors, which in general are going through a rapid commoditization and profit-squeezing trend. To understand what’s driving the MEMS microphone market, consider that the Apple iPhone 7 and 7S each have 4 MEMS microphones. As reported by System Plus Consulting, the latest iPhones have “a front-facing top microphone, presumably f... » read more

The Trouble With MEMS

By Ed Sperling - 25 May, 2016 - Comments: 0

The advent of the Internet of Things will open up a slew of new opportunities for MEMS-based sensors, but chipmakers are proceeding cautiously. There are a number of reasons for that restraint. Microelectromechanical systems are difficult to design, manufacture and test, which initially fueled optimism in the MEMS ecosystem that this market would command the same kinds of premiums that analo... » read more

MEMS Foundries Play Waiting Game

By Mark LaPedus - 18 Jul, 2013 - Comments: 0

By Mark LaPedus For years, the foundries in the microelectromechanical systems (MEMS) business have been patiently waiting for the MEMS integrated device manufacturers (IDMs) to outsource some or all of their production. The MEMS foundries are still waiting for that development. Because MEMS are custom devices tuned to a proprietary process and toolset, IDMs still prefer to use their own f... » read more
