This paper presents an improved design of the electrodynamic CMOS-MEMS microphone. The studied microphone is based on two integrated concentric planar inductors, a fixed outer one and an inner one ...

Abstract: Inertial navigation systems (INS) are widely recognised for providing precise location, velocity, and attitude data over short durations. However, their accuracy deteriorates over time. To ...

These MEMS devices have a vulnerability where the electromagnetic emissions can be detected, even through a wall, using AI to reconstruct the voices that the microphone picks up. The researchers at ...

Radio trick secretly turns laptop into a spy speaker that talks through walls Researchers reveal hack that turns everyday microphones into spying tools. Updated: Jun 12, 2025 08:30 AM EST ...

There is a lot of demand for the tiny speaker in smart glasses and smartwatches to be even smaller and lighter. However, the century-old micro-speakers built around a dynamic driver, coil, and ...
