Abstract

Intelligence is built on processing information gained through interfaces to the environment, the sensors. Therefore, apart from the processing capability, it is the amount and quality of information that determines the level of intelligence that a smart system is able to achieve. Utilizing our in-house capacitive MEMS technology, Infineon’s ambient sensing solutions offer the performance characteristics required for building intelligence into the systems of the future.

Infineon has continuously innovated MEMS microphones and is now introducing the third MEMS technology generation with again improved acoustic performance. High signal-to-noise-ratio (SNR) microphones are needed for detecting speech in noisy environments, while their high dynamic range enables the clear capturing of voice despite loud background sources. In addition, miniaturization allows for seamless integration into any system, from smartphones to home appliances. Finally, similar capacitive MEMS principles are used in new applications such as Infineon’s highly accurate barometric pressure sensor or the photoacoustic gas sensor, enabling systems with wider sensing abilities.
