The first product based on the revolutionary technology from sensiBel will be officially launched at the Sensors Converge conference and exhibition, taking place June 24-26 in Santa Clara, CA. In a pivotal moment for the optical MEMS microphone pioneer, the SBM100B digital output microphone is now commercially available and will be demonstrated publicly at the event. The SBM100B family includes PDM and I²S digital audio interfaces, as well as an 8-channel TDM configuration for beamforming and microphone arrays.
Sensors Converge, formerly known as Sensors Expo & Conference, has expanded its relevance in the audio industry, with this year’s event seeing a record number of announcements for MEMS devices and sensor fusion of AI-based, real-time adaptive audio. Based on many years of research, the sensiBel SBM100B is the first MEMS microphone product to use interferometry-based laser optical sensing technology in a tiny package. The first product in the sensiBel roadmap, the SBM100B is a finalist for the prestigious Best of Sensors award at the show.
The sensiBel SBM100B is the first MEMS microphone to successfully deliver studio-quality audio in a compact, production-ready format. With specifications including 80dBA SNR, 146dB SPL Acoustic Overload Point (AOP), and a 132dB dynamic range, the SBM100B far outperforms traditional capacitive MEMS microphones. In fact, the optical technology developed by the Norwegian company, based on years of research at SINTEF, one of Europe’s largest independent research organizations, is able to rival typical electret condenser microphones (ECM) in pure signal performance. And in many applications, the SBM100B will reveal a much larger potential due to its manufacturability, device consistency, and on-chip digital output, even allowing instrumentation-grade designs.
The SBM100B uses laser interferometry to detect membrane movement with extreme precision, allowing for a dynamic range and noise floor not possible with traditional MEMS technologies. This innovation enables ultra-high-fidelity sound capture, opening the door to new applications in mobile devices, true wireless stereo (TWS), smart speakers, wearables, conferencing systems, and beyond.
The sensiBel SBM100B microphone is delivered in a small surface-mount reflow-solderable bottom port package, supporting PDM, I²S, and TDM8 digital interfaces, making it seamless for integration into a wide range of high-volume consumer and industrial applications.
“The SBM100B represents a major leap forward in MEMS microphone technology,” says Sverre Dale Moen, CEO of sensiBel. “We are thrilled to bring optical sensing to market in a form factor that meets the performance and scalability needs of real-world applications.”
To support volume manufacturing, sensiBel is working with AAC Technologies as its assembly and test manufacturing scaling partner. AAC is a leading manufacturer of very high-volume MEMS microphones to the industry, and their proven capability allows sensiBel to quickly and efficiently scale production.
“The SBM100B is the first product in sensiBel’s roadmap. Future generations will continue to push performance boundaries, building on this foundation to enable new use cases in professional audio, automotive, and spatial audio,” the company states.
