Countering Drones with Animal-Inspired Robots, Acoustic Sensors, AI and More

The UK Ministry of Defence’s innovation hub, the Defence and Security Accelerator (DASA), has awarded a total of £2m to 18 separate projects that aim to develop new capabilities to detect, disrupt and defeat the hostile and malicious use of drones. The contracts are the result of the Countering Drones competition launched earlier this year.…

MEMS in CMOS: An Impossible Dream?

European startup Nanusens, based in London and Barcelona, has an ambitious technology goal: reliable, inexpensive CMOS microelectromechanical-system (MEMS) devices that can be built on the same die as their interface ASIC. The space savings would be game-changing for consumer electronics. Building MEMS in CMOS shouldn’t really be possible. CMOS was not designed for mechanical structures;…

Robust MEMS Sensors Are a Sound Choice for Audio

Microelectromechanical system (MEMS) technology offers robustness and reliability for microphones and loudspeakers used in consumer voice-control implementations as well as for the more extreme environments of industrial applications. The sensors have become increasingly integrated with other components of the audio signal-processing chain, allowing smaller microphones with analog or digital output. Inside the package, the transducer…
