sensiBel Aligns with Silex Microsystems for High-Volume Production of Its Studio-Quality MEMS Microphone

Posted - May 4, 2026

Optical MEMS innovator engages the world’s largest pure-play MEMS foundry to manufacture its high SNR MEMS microphone

sensiBel, the pioneer in optical MEMS sensing, today announced a supply-chain relationship with Silex for the manufacture of its microelectromechanical systems (MEMS) microphone — which uniquely uses a precision optical detection module to deliver professional-grade audio in a compact, production-ready format.

“sensiBel’s miniaturized digital optical MEMS microphone delivers the same audio recording quality that users experience with pro-style studio microphones. That’s driving immense customer excitement,”

said Kieran Harney, CEO, sensiBel.

“Scaling mass production with Silex, the industry’s number one pure-play MEMS foundry, assures our customers that we can meet their volume demands for our microphone.”

Inside sensiBel’s optical MEMS microphone

sensiBel’s optical MEMS microphone platform features a traditional ASIC and MEMS sensor, combined with a precision optical measurement module that captures the displacement of the MEMS -based diaphragm.

These components form sensiBel’s studio-quality digital optical MEMS microphone — which achieves a remarkable 80dB signal-to-noise ratio (SNR), 146dB SPL acoustic overload point (AOP), and a dynamic range of 132dB — dynamic range levels that far eclipse those of the traditional capacitive MEMS microphones first commercialized in the early 2000’s.
