Researchers have fabricated a hair-thin microphone made entirely of silica fiber that can detect a large range of ultrasound ...
A newly developed fiber-optic microphone demonstrates how light-based sensing can overcome the limitations of conventional electronics in extreme environments.
Researchers have created a microphone so thin it looks like a human hair, yet tough enough to survive temperatures as high as 1,000°C. Made entirely from silica glass, this tiny device can detect ...
