Next-gen MEMS microphone sports 73 dB SNR, high acoustic overload point
Infineon is launching a next-generation analog MEMS microphone that renders even better results – the XENSIV MEMS microphone IM73A135. In microphones, designers often have to accept trade-offs: high signal-to-noise ratio (SNR), a small package, high acoustic overload point, low power consumption, MEMS versus electret condenser microphones (ECM). For this reason, applications that require the highest […]

Compared with OmniVision’s prior-generation […]
Three-axis MEMS accelerometer optimized for industrial vibration sensing
STMicroelectronics, is powering the next generation of Industry 4.0 applications with a new vibration-sensing solution optimized to enable smart maintenance of factory equipment. ST’s IIS3DWB vibration sensor and supporting STEVAL-STWINKT1 multi-sensor evaluation kit accelerate development of condition-monitoring systems that boost productivity by inferring equipment maintenance needs. Analyzing the sensed vibration data locally or in the cloud helps owners create […]
The difference between CCD and CMOS image sensing
Charge-coupled devices (CCDs) and complementary metal-oxide-semiconductor (CMOS) technology have been in fierce yet friendly competition. Fierce because valuable market share is contested, friendly because the rival digital camera technologies have much in common. It is ironic that the more-costly CCD sensor is used in the most advanced astrophotography instruments and also in low-end point-and-shoot cameras, […]
How can sensors predictably fulfill a market need?
At Sensor Expo 2017, Roger Grace, president of Roger Grace Associates, a marketing consultancy that specializes in sensors and microelectromechanical system (MEMS) devices, explains the role that marketing should play in new product development and product introduction. Roger has frequently published many articles on the topic that are available through links on his website. In […]
High-performance MEMS capacitive accelerometers feature improved temperature performance, scale factor and bias temperature shifts
Silicon Designs Inc. has announced the global market introduction of six new series of low-cost, high-performance MEMS capacitive accelerometers, in both traditional and smaller footprints. These include the single axis Model 2220 or triaxial Model 2470, featuring aluminum housings and a standard 1 meter integral cable; the single axis Model 2240 or triaxial Model 2480, featuring […]
How does analog to digital conversion impact sensor accuracy?
When an analog sensors’ output is converted to a digital output with an analog to digital converter (ADC), conversion resolution, conversion accuracy, conversion speed or bandwidth, inherent system noise levels, and power consumption are all ADC tradeoffs. Errors due to temperature, supply voltage, linearity, quantizing, and other factors may reduce the accuracy of an ADC […]
What are common ways to protect a sensor from harmful exposure?
For a sensor, the amount of harmful exposure it receives from the environment and harmful constituents in the measuring process depends on what is being sensed and the environment itself. Different packaging is required to cope with and survive the specific situation. Two major considerations for protection are at the sensing element/transducer level or at […]
