We develop the next generation MEMS microphone. The vast majority of microphones used today are based on the same basic principle as invented more than a 100 years ago. sensiBel is breaking with this principle and introduces optical technology to the microphone.

The best of two worlds in one package
Application designers are typically faced with the choice of using a MEMS microphone with sub-optimal performance or a higher performance Electret Condenser Microphone (ECMs). ECMs are large in size and inherently not suitable for high-volume production.
The choice for emerging and demanding applications is now made easy with the true studio-quality optical MEMS microphone that offers the best of two worlds.
The optical technology
sensiBel’s patented optical MEMS technology that makes the microphone so sensitive is based on a combination of two optical phenomena; interference and diffraction, both of which are due to the wave character of light. The microphone uses a tiny energy-efficient laser to measure extremely accurately the displacement of a silicon-based membrane, thanks to the integrated photodetector readout system.
