Thermography is the front-line sensing technology to detect and isolate victims of the coronavirus (COVID-19). The non-contact thermal sensors have been ubiquitous over the past few weeks as the numbers of those contracting the virus and dying as the result of it have risen. Accuracy of the infrared (IR) thermometer gun’s measurements depends on several […]

How do sensors make a building more comfortable?
Temperature is certainly the most obvious answer but there are other sensors that are increasingly being employed in the smartest homes and buildings. With the right sensor inputs, several actions can be taken by actuators to increase health/safety as well as comfort. In addition to temperature measurements, pressure, humidity and air quality sensing in ducts […]
8 µm pitch, dual-band infrared imaging IC optimizes infrared imaging systems
Senseeker Engineering has announced the availability of the Oxygen RD0092, the world’s first 8 µm pitch dual-band digital readout IC (DROIC). The Oxygen RD0092 supports a 1280 x 720 frame size at over 500 fps and dual-polarity inputs to provide compatibility with all industry-standard direct-injection detector materials. The solution was designed to optimize infrared imaging […]
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 of […]
How can lasers be used for touch sensing?
At Sensors Expo 2019 in San Jose, CA, Bengt Edlund, the Vice President of Distribution & Partner Sales for Neonode Inc. demonstrates the touch sensing capabilities that Neonode’s ZForce AIR sensor module can provide to non-glass surfaces. The laser light based touch sensor provides a unique approach to increasingly common touch sensing applications and enables […]
OmniVision expands resolution to 4 megapixels in image sensor family
OmniVision Technologies, Inc., a developer of advanced digital imaging solutions, has announced the OS04A10, a 2.9 micron pixel image sensor with 4 megapixel (MP) resolution, the latest addition to its growing family of Nyxel near-infrared (NIR) and ultra-low light (ULL) sensors. The OS04A10 provides security cameras with greater zoom range and AI-enabled surveillance systems with […]
What’s the secret to increasingly smaller sensors?
Actually, it’s no secret, but microelectromechanical systems (MEMS) and integrated circuit technology provide breakthroughs in size and the ability to further decrease size with next-generation designs. The breakthroughs can occur both in the research & development area and in volume production. In the R&D area, CEA-Leti has prototyped a next-generation optical chemical sensor using mid-infrared […]
What’s new in sensors for autonomous vehicles? Part 1
Tesla, one of the leaders in autonomous, self-driving vehicles boasts 8 vision cameras, 12 ultrasonic sensors and radar on all of the vehicles it is currently building according to recent company tweet. To make the right decisions by using the data from these sensors in the timeliest manner through sensor fusion, Tesla has developed a […]
What is an oximeter?
Unlike an oxymoron (äksəˈmôrˌän: a combination of contradictory words), a (pulse) oximeter (äkˈsimidər) is a sensing technique to measure oxygen saturation in a person’s peripheral (capillary) blood (SpO2). Using pulses in the capillaries of the tested area, the noninvasive measurement helps to evaluate a variety of medical conditions that affect the function of the heart […]
How can touch-free sensing protect public health?
Many communicable diseases, such as viruses and bacterial infections, are transmitted by direct contact with a person who has the disease or with something that person touched. Avoiding contact is an obvious way to prevent spreading diseases. Touch-free sensors allow many frequently accessed functions in restrooms, such as automatic hands-free urinal and toilet flush, hands-free […]
