Part 1 of this article looked at sensing and sensors for ultracold and cryogenic temperatures; Part 2 advances the story to more esoteric situations. Q: What’s the fundamental difference between measuring extremely high temperatures versus cryogenic ones? A: When things get really hot, extending into thousands of degrees, the sensor options are limited. Usually, it […]
How can an RTC feature stabilize an image sensor’s output?
At Sensors Expo 2019 in San Jose, CA, Sahil Choudhary, a product marketing manager at InvenSense, demonstrates how the real-time clock (RTC) feature in his company’s 6-axis (accelerometer and gyroscope) sensors provides accuracy and stabilization for critical imaging applications. For a specific device frequency, say 10 Hz, the RTC input ensures that the 10 Hz […]
What are cryogenic temperature measurements? Part 1
Cryogenic temperatures may seem only of limited interest, but they are actually critical in many instrumentation and other systems. Measuring these ultralow temperatures is both easy and difficult, depending on temperature, material, and mass. Temperature is the most commonly measured physical variable, whether it’s just to assess the local weather to manage the performance of […]
What makes a winning sensor?
At Sensor Expo 2019 in San Jose, CA, Travis Taylor, an Associate MTS at Maxim Integrated, demonstrates the Health Sensor Platform 2.0 that won the Sensors Expo 2019 Innovative Product of the Year Award. It can measure electrocardiogram (ECG), optical heart rate and temperature. In addition to its wrist-worn display, the measured information can be […]
High-precision displacement sensors and systems ideal for rocket engine validation testing
The Measuring Division of Kaman Precision Products, Inc. announces the availability of its line of Extreme Environment high-precision displacement sensors and systems. With their proven design and rugged all-welded and hermetic construction, the sensors and systems are ideal for rocket and turbine engine validation testing. They are also an excellent choice for other applications that […]
How can you achieve a low power sensor node?
At Sensors Expo 2019 in San Jose, CA, Chet Jewan, Vice President of Sales and Business Development at Eta Compute, describes the demos in his booth. The sensor node consists of the Eta Compute ECM3531 application specific integrated circuit (ASIC), a ROHM Semiconductor RF device and sensors – all running off of a small solar […]
What’s missing from many smart homes today?
In the home of the future, many different types of sensors will allow the owner and authorized users to activate several functions remotely. To avoid unauthorized users from accessing these systems and even gaining entry into the home, security must be designed in. At Sensors Expo 2019 in San Jose, Steve Hanna from Infineon who […]
What information does a proximal flow sensor provide?
At Sensors Expo 2019 in San Jose, CA, Lucas Tschuor, Head of Field Application Engineering at Sensirion, explains how his company’s proximal flow sensor is used in respiratory applications with the help of a teddy bear. With a very sensitive device, breathing cycles can be detected and help the patient breathe providing an ideal sensor […]
Wire energy harvesting components
POSITAL’s Wiegand assemblies offer a compact and efficient way of harvesting power for electronic circuits in electromechanical devices, eliminating the need for backup batteries. The operating principle of POSITAL’s Wiegand modules is simple. A “Wiegand wire” is a short length of specially prepared Vicalloy (vanadium-iron-cobalt) wire. When exposed to a changing external magnetic field (e.g. […]
How can you have touchless touch sensing?
At Sensors Expo 2019 in San Jose, CA, Håkan Persson, CEO of Neonode Inc., demonstrates touchless sensing using his company’s vertical-cavity surface-emitting laser (VCSEL) technology. Neonode’s zForce® (zero force) patented optical sensing technology uses infrared light, invisible to the human eye to provide a holographic touch screen, essentially making air touchable. The holographic design consists […]
