The uses for microelectromechanical systems (MEMS) devices have grown exponentially. Applications for MEMS technology include actuators, sensors, inertial measurement units (IMUs), energy harvesters, pumps, motors, oscillators, resonators, and more. They are used in all areas, from consumer to medical, military, and space. Two keys to the expansive uses of MEMS devices include the ability to […]

Clock oscillator achieves 0.2 ppm frequency tolerance
Depending on temperature range, the SiT7910 Super TCXO from SiTime can attain frequency stability of less than 0.1 ppm. Clock oscillator circuits serve two functions. They provide a clock timing signal for digital circuits such as microprocessors and they keep track of time, often for time-stamping of events. While oscillators for digital circuits typically produce […]
MEMS microphone trio address ear and wearables market
Knowles Corporation introduces its latest series of SiSonic MEMS microphones: Titan (Digital), Falcon (Differential Analog), and Robin (Single Ended Analog). The new trio of microphones provides advanced performance capabilities for space-constrained Ear and wearable applications like True Wireless Stereo (TWS) earbuds, smart watches, Augmented Reality (AR) glasses, and Virtual Reality (VR) headsets. Each of the […]
What are MEMS relays good for?
MEMS relays (also called MEMS switches) have high isolation when open and very low insertion loss or resistance when closed; they can handle signals from DC to multi-GHz, operate with very little power, and their micrometer size means that many can be packed into a small space. These attributes make MEMS relays well-suited for 5G […]
MEMS mics optimized for active noise cancelation apps
CUI Devices’ Audio Group today announced the addition of two MEMS microphone models designed for active noise cancellation. The CMM-2718AB-3815NC-TR and CMM-2718AT-3817NC-TR are analog MEMS microphones featuring omnidirectional directivity and bottom or top port locations, respectively. Thanks to their flat frequency response from 20 to 10,000 Hz, high signal-to-noise ratios (SNR) of 62 or 64 dBA, and high acoustic overload points (AOP) of […]
What can you make with MEMS technology?
Microelectromechanical systems (MEMS) has several names, including micro-electro-mechanical systems, and micromechatronic systems. In Japan, MEMS is called micromachines, while in Europe, it’s referred to as microsystem technology (MST). Whatever name that’s used, MEMS devices are made using components measuring from 1 to 100 μm (0.001 to 0.1 mm), with MEMS devices ranging from 20 μm […]
MEMs microphones feature high SNR, wide dynamic range
TDK Corporation introduces three new MEMS microphones as part of the SmartSound family of products for mobile, IoT, and other consumer devices. Each of these high-performance microphones pushes the boundaries of microphone acoustic performance, providing advanced feature sets with very low power in small package footprints. The SmartSound family of MEMS microphones from TDK are […]
