• TRUMPF Venture leads investment round of 15 million euros in Norwegian startup sensiBel
• Mini microphones enable studio-quality recordings thanks to optical MEMS / High market volume: experts forecast sales of eight billion MEMS microphones in 2022
Such microphones are just as compact as other MEMS-based solutions on the market and deliver a significantly better quality of sound. “TRUMPF Venture is investing in sensiBel and will also provide strong support in the area of photonics,” says Dieter Kraft, managing director of TRUMPF Venture GmbH. “The optical MEMS microphone developed by sensiBel marks a real breakthrough capable of delivering studio-quality sound recordings. This technology enables speech recognition over greater distances and also in loud environments.” sensiBel (sensibel.com) currently has a workforce of around 20 employees. MEMS microphones are found not only in consumer electronics but also in, for example, medical devices and applications in the automotive industry. Experts forecast a market volume for MEMS microphones of eight billion units in 2022 alone.
Reaching new levels of sound quality
The investment round led by TRUMPF Venture GmbH involved the fund of the European Innovation Council (EIC Fund) and other venture capital investors from Norway, among others. “Based on tests with customers, we have been able to demonstrate a quality of transmission that was not technically feasible before the development of our microphone,” says Sverre Dale Moen, CEO of sensiBel. “With the backing of our investors, we can now move forward with international marketing.” sensiBel intends to use the new capital to ramp up mass production of MEMS microphones and to expand its research and development activities.
Measuring sound by means of laser
MEMS microphones function by means of a membrane which is set in motion by sound waves. In the case of a conventional, capacitive MEMS microphone, this movement of the membrane is measured on the basis of changes to an electrical field between the movable membrane and a rigid backplate. By contrast, the optical system in the sensiBel microphone uses light waves to measure this movement. Light is projected onto the membrane, via a diffraction grating, by means of a vertical-cavity surface-emitting laser (VCSEL). This light is reflected and then captured and analyzed by photodiodes. Unlike the conventional method, this new technology enables the measurement of very small movements of the membrane and therefore very low levels of noise.
