MEMS accelerometers enable early detection of structural defects
Analog Devices has announced two three-axis MEMS accelerometers that perform high resolution vibration measurement with very low noise to enable the early detection of structural defects via wireless sensor networks. The low power consumption of the ADXL354 and ADXL355 accelerometers lengthens battery life and allows extended product usage by reducing the time between battery changes.
The quantum sniffer dog
As humans, we sniff out different scents and aromas using chemical receptors in our noses. In technological gas detection, however, there are a whole host of other methods available. One such method is to use infrared lasers, passing a laser beam through the gas to an adjacent separate detector, which measures the degree of light attenuation it causes.
Force-sensing technology provides smarter UI for tablets
Developer of force-sensing technology, Peratech, is aiming to give users of smartphones and tablets a more intuitive user experience while unleashing more creative opportunities for product and app developers by adding new ways for consumers to interact with their devices.
UL approval awarded to bimetal probe thermostats
The line of Bimetal Probe Thermostats from Selco is officially approved with UL (E145478, XAPX2), c-UL E145478(XAPX8) certifications. In addition to UL approvals, these are also RoHS compliant. This is a very exciting time for Selco as more and more customers are required to have UL approval on their finished product which includes all components that are used within.
Teaming up for simple and precise measurements
The new distance-measuring inductive sensors IR08, IR12 and IR18 from the Baumer AlphaProx family offer easy and reasonably priced analysis of the measurement results without any additional cost or effort for programming, thanks to linearised calibration curves and very low standard dispersion rates.
Are sensing technologies impacting our future?
Consumer applications, especially smartphones and tablets, have been the main driver of the MEMS and sensors industry for some time now. Today, a general slowdown has been clearly identified by the players and confirmed by the Yole Développement (Yole) report, Status of the MEMS Industry (Yole Développement, May 2016).
Type of AFM uses nanowires as tiny sensors
A type of atomic force microscope (AFM) uses nanowires as tiny sensors. Unlike standard AFM, the device with a nanowire sensor enables measurements of both the size and direction of forces. Physicists at the University of Basel and at the EPF Lausanne have described these results in the recent issue of Nature Nanotechnology.
Filter membrane protects sensor from water and dust
Manufacturer of humidity, temperature and flow sensor solutions, Sensirion, offers an on-package filter membrane option for selected humidity sensors in the SHT3x series. The SHT3x membrane is a PTFE film that protects the sensor opening from water and dust according to IP67.
Meridian Hydrogen Sensor is now available
The new Merdian Hydrogen (H2) Sensor has been released by Tyco Gas & Flame Detection.
Transparent sensors for imaging the brain
In 2014, when University of Wisconsin–Madison engineers announced in the journal Nature Communications that they had developed transparent sensors for use in imaging the brain, researchers around the world took notice. Then the requests came flooding in. “So many research groups started asking us for these devices that we couldn’t keep up,” says Zhenqiang (Jack) Ma, the Lynn H. Matthias Professor and Vilas Distinguish...
