Understanding electret condenser microphones
Electret condenser microphones (ECMs) are widely used in audio applications due to their small size, low cost, and high sensitivity. They operate using a permanently charged diaphragm and backplate, eliminating the need for external polarization. This makes them ideal for use in consumer electronics, hearing aids, and professional audio equipment. Their ability to deliver a […]
MEMS sensor line expanded with automotive-grade IMUs
TDK Corporation has expanded its InvenSense SmartAutomotive™ MEMS sensor lineup with two new 6-axis IMUs: the IAM-20685HP and IAM-20689. These second-generation sensors are designed for automotive safety applications and have entered mass production, with samples currently available. The IAM-20685HP achieves ASIL B certification on technical safety requirements and operates at temperatures up to 125°C. Its […]
Web-based tool trains smart sensors using AI/ML
ST AIoT Craft, a new web-based tool from STMicroelectronics, simplifies developing and provisioning node-to-cloud AIoT (Artificial Intelligence of Things) projects that use the machine-learning core (MLC) of ST’s smart MEMS sensors. The MLC is unique to the ST MEMS portfolio and enables decision-tree learning models to run directly in the sensor. Capable of operating autonomously, […]
How will NHTSA’s AEB mandate impact sensing?
In 2019, the U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) published a draft pedestrian automatic emergency braking (PAEB) test procedure. When, the results of testing conducted in 2022 on 12 light vehicles were published in 2023 (2022 Light Vehicle Pedestrian Automatic Emergency Braking Test Summary, March 2023), one conclusion was: No vehicles […]
How sensors help you play ball: part 2
A FIFA-compliant match ball from Adidas has a TDK InvenSense 6-axis MotionTracking device and other electronics mounted in the center of the ball. As shown in Figure 1, the Adidas patented suspension system stabilizes the electronics module. Instead of having the sensing/communication module mounted on the surface of the ball near the inflator valve, the […]
Waterproof MEMS microphone carries IPX7 rating
CUI Devices’ Audio Group announced a new waterproof MEMS microphone that is ideal for harsh environments. The CMM-3424DT-26165-TR MEMS microphone carries an IPX7 waterproof rating for applications where moisture and liquid ingress are a concern. Housed in a compact, surface mount package measuring 4 x 3 x 1 mm, this waterproof MEMS microphone features a digital […]
T5838 MEMS microphones preferred choice for edge AI applications
TDK Corporation announces that its low-power InvenSense T5838 and T5837 digital PDM microphones, part of the SmartSound™ family, have established themselves as the microphone of choice for low-power edge AI application processors that perform keyword detection due to its innovative Acoustic Activity Detect (AAD) feature that enables system power savings, thus prolonging battery life, and […]
Has integrated sensor and circuitry reached a new milestone?
Since the earliest days of microelectromechanical systems (MEMS) sensor products, the goal of easily combining the sensing structures made using MEMS processing with the required signal conditioning has driven many sensor R&D labs. If successful, the solution would make the resulting devices more useful in a broader range of applications. In the 1980s, the circuitry […]
