Automotive MEMS accelerometer optimizes for sensing road noise, vibration
STMicroelectronics is enabling more acoustically comfortable cars, with its new sensor for road-noise cancellation (RNC) through active noise-control (ANC) techniques. Cars have traditionally been defined by engine performance, exterior design, and powertrains, but drivers and passengers are increasingly focused on comfort. Indeed, while Electric Vehicles (EVs) are intrinsically less noisy than internal combustion engine […]
What are today’s challenges for MEMS? Pt 2
In contrast to the findings in Part 1, Yole Intelligence, part of Yole Group, analysis of the MEMS market was quite different [1]. It found that 2021 was an exceptional year for MEMS companies. Its annual and best-selling MEMS report [2], which was first released in 2004, projects that an almost $22B MEMS market will […]
MEMS 2021 report card: C+
Sensors marketing consultant Roger Grace has issued his 2021 MEMS Commercialization Report Card. Do you agree with his conclusions?
What are today’s challenges for MEMS? Pt 1
Since the initial market introduction of microelectromechanical systems (MEMS) products from pressure sensors to accelerometers to more recent gas sensors and several others, users and potential users have been attracted to the technology for many reasons. This includes its incredibly small size, low weight, low power consumption and low cost – especially as high-volume manufacturing […]
MEMs transducer packaged in ultra-compact PCB assembly
Posifa Technologies introduced its new PVC4100 series fully calibrated MEMS Pirani vacuum transducer. Designed for cost-effective OEM integration, the device consists of a surface-mount MEMS Pirani sensor and microcontroller-based measuring electronics — all packaged in an ultra-compact PCB assembly featuring a connector-terminated wire harness. The PVC4100’s sensor element is based on Posifa’s second-generation MEMS thermal […]
How can you easily evaluate a MEMS microphone ?
Microelectromechanical systems (MEMS) technology is used for many sensing applications including microphones. The MEMS microphone provides a design alternative to Electret Condenser Microphones (ECMs) for many consumer electronic and mobile products. With this goal in mind, Infineon Technologies silicon microphones have been designed to extend the benefits of lowest possible self-noise (high SNR) and lowest […]
Advanced MEMS sensors from STMicroelectronics power-up the onlife era
STMicroelectronics is introducing its third generation of MEMS sensors. The new sensors enable the next leap in performance and features for consumer mobiles and smart industries, healthcare, and retail. MEMS technology is the cornerstone of the robust and chip-sized motion and environmental sensors that drive the intuitive context-aware features of today’s smartphones and wearables. ST’s latest […]
Sensor processing unit integrates DSP to run AI algorithms and MEMs sensors on same silicon
STMicroelectronics announced the launch of the Intelligent Sensor Processing Unit (ISPU) that combines a Digital Signal Processor (DSP) suited to run AI algorithms and MEMS sensor on the same silicon. In addition to reducing size over system-in-package devices and cutting power by up to 80%, merging sensor and AI puts electronic decision-making in the application Edge. Here, it […]
How can a MEMS microphone be used in harsh environments?
The answer depends on how harsh of an environment and how much protection is required. For a microelectromechanical systems (MEMS) microphone, one of the most-harsh environments is the human body, since sweat and dirt can cause failures in traditional MEMS microphone architectures. Regarding the protection, the International Electrochemical Commission’s (IEC’s) IEC 60529 rating system defines different […]
