Innovating For A Greener Future: The Role Of MEMS Microphones In Driving Sustainable And Energy Efficient Consumer Electronics

As a globally leading supplier of MEMS microphones, Infineon has been driving audio innovation by enhancing SNR, AOP, and power consumption to pioneer new use-cases such as ANC in TWS and studio-quality audio recording with laptops. As the trend for better audio in communication and recording continues, new requirements have moved into the focus of device manufacturers. Sustainability, including extending the lifespan of products, recycling, and eco-design, is no longer an afterthought but has become a major sales argument. EU authorities are accelerating the trend through regulations and ecodesign labels, with the goal of shifting to a circular economy model and moving away from a linear economy model that consists of producing, consuming, and dumping.

MEMS microphones are particularly vulnerable components requiring external shielding against liquids, dust, light, ultrasound, compressed air, and electromagnetic interference. Through forward integration, our next generation of XENSIV™ MEMS microphones will take care of their own protection, thus lowering integration, testing, and repair costs. At Infineon, we believe that our next generation of XENSIV™ MEMS microphones can contribute to more sustainable and energy-efficient consumer electronics while maintaining superior audio quality.

Infineon Technologies AG

Dr. Gunar Lorenz is currently heading the technical marketing and application engineering for consumer sensors at Infineon Technologies. Gunar joined Infineon in 2016 as system project manager responsible for Infineon’s first open market MEMS microphone. Prior joining to Infineon he worked as director of system-level simulation at Coventor, where he and his group invented and developed Coventor’s MEMS/IC co-simulation design environment MEMS+. The original ideas for MEMS+ are embodied in his PhD carried out at Robert Bosch R&D Center in 1999. Gunar graduated in mechanical engineering at the TU Braunschweig in Germany and received his PHD in electrical engineering from the TU Bremen in 1999.

Here at Infineon, we combine entrepreneurial success with responsible action to make life easier, safer, and greener. Barely visible, semiconductors have become an indispensable part of everyday life. We play a key role in shaping a better future – with microelectronics that link the real and the digital world. Our semiconductors enable efficient energy management, smart mobility, as well as secure, seamless communications in an increasingly connected world. Infineon designs, develops, manufactures and markets a broad range of semiconductors and system solutions. The focus of its activities is on automotive and industrial electronics, communication and information technologies, IoT, sensor technology and security. The product range comprises standard components, software, customer-specific solutions for devices and systems, as well as specific components for digital, analog, and mixed-signal applications.
