To measure and classify a wide range of combustible gases, NevadaNano has integrated multiple, complementary chemical sensors on a single silicon chip called the Molecular Property Spectrometer or MPS sensor. The chip’s patented array of micro-cantilevers with integrated piezoelectric sensing elements provides electrical actuation and sensing of resonance frequency. Monitoring resonance is a highly sensitive […]
What is anosmia?
One of the common symptoms of COVID-19 is loss of smell or anosmia. This is not uncommon for patients with viral upper respiratory infections. The good news is this is temporary in most cases. The bad news is this prevents the personal detection of odors associated with critical odors from gas leaks, smoke from fires […]
What is photoacoustic spectroscopy (PAS)?
Identified in the 19th century, the photoacoustic effect allows the conversion of light into sound and has been employed in devices such as non-dispersive infrared absorption spectroscopy (NDIR), which was the first commercially available device to detect gases using this effect. Modulating the light intensity produces a periodic pressure variation, which is measured with a […]
How can a load cell force sensor be used in increasingly smaller end products?
A smaller form factor is frequently on the must have list for many next generation products. However, compromising performance is usually not an acceptable tradeoff. This is especially true in medical products such as force sensors where both precision and miniaturization are required. For example, vascular clamps are used to reduce the flow of blood […]
What are the results of the 2019 MEMS Industry Commercialization Report Card survey?
Since microelectromechanical systems (MEMS) technology involves numerous sensors from pressure sensors to accelerometers, gyroscopes and more and actuators such as microvalves, micromotors, micromirrors and more as well as many new areas, there should be broad industry interest in the results of the 2019 report card. The MEMS Industry Commercialization Report Card is a survey of […]
What’s new in temperature testing for COVID-19?
When COVID-19 appeared earlier this year, the first wide-spread testing to detect if a person had the disease involved temperature. In contrast to other invasive approaches, the need for improved temperature testing prompted a few companies to investigate and then develop their own approach. Dermal Photonics Corp. solution was a wearable smart thermometer called NIRA […]
How do you make iconic industrial moving equipment safer?
In the case of Bobcat construction equipment, you add radar-based sensing solutions to detect objects and people on job sites. Partnering with Ainstein AI, Inc., Doosan Bobcat North America is doing just that. Bobcat’s are frequently seen loading or unloading trucks, moving or leveling dirt, drilling, cleaning up at various locations and other activities where […]
How can you live better in spite of vision impairment?
People who are visually impaired or even blind can now read the text from a book, smartphone screen or other surfaces. This is possible thanks to a voice-activated device that attaches to the frame of virtually any glasses. The OrCam MyEye uses an advanced 13 megapixel optical sensor that captures an image of the user’s […]
How can you quickly integrate an Ozone sensor into your final design?
First, you must have an ozone sensor that meets your application’s requirements. Must haves could include: Measurement Range 0 to 20 ppm Lower Detection Limit <0.1ppm Resolution <0.1ppm Accuracy <± 2% of reading Small Size with Low Profile (15x15x3mm) Long Life (10 years expected life) Fast Response (15 seconds typical) Long Term Stability (50 ppm […]
How do you track an elephant?
Very carefully might be your first response but there is a technical answer as well. The technical answer involves a design challenge called ElephantEdge to create the world’s most advanced tracker to protect elephants in their natural habitats from poachers, trophy hunters and habitat destruction. Supported by Hackster.io, an Avnet community, and Smart Parks, a […]
