The current emphasis on providing products and materials with fewer environmental effects will have a direct impact on the chemical industry and chemical sensors. Obviously, this starts with, but is certainly not restricted to, reduced CO2 emissions. Chemical sensors have a wide range of applications, including healthcare, industrial, biotechnology, and household sensing requirements such as […]

How does air quality history impact data analysis?
Measuring air quality, like any other measurement process starts with the sensors. The sensors provide the concentration of different elements in the air such as CO2 and volatile organic compounds (VOCs) as well as other parametric data such as humidity, temperature, atmospheric pressure and light level that affect the ambient environment indoors – or outdoors. […]
How can low-cost sensors help address climate change?
According to the recent IDTechEx report “Printed and Flexible Sensors 2022-2032: Technologies, Players, Markets,” low cost printed/flexible sensor technologies could play a significant role in adapting to climate change [1]. Adapting could take various forms, from changing the areas in which specific crops are grown to building flood defense systems and even relocating cities in more […]
How can sensors help cleanup waterways?
Twenty years after its first-generation design was introduced (2002), iRobot’s Roomba has spawned many competitors for indoor cleanup and made several advancements to its initial capabilities. Interactive Autonomous Dynamic Systems (IADYS) has applied the autonomous robot concept to address cleaner and safer water in rivers, canals, lakes, ponds, shipyards and more. IADYS’ Jellyfishbot autonomously collects […]
How is biomarker sensing expanding?
Pathogens, infectious agents that cause disease, can include microscopic viruses, bacteria, fungi and protozoa. Both biomarkers and biosensors can detect and identify pathogenic agents. After using biomarkers to measure and detect pathogenic factors and assess biological conditions., drugs can be delivered to the target tissue so that other tissues are not damaged. Biomarkers are widely […]
Can a dog’s sense of smell be duplicated? Part 1
Dogs’ sensitive noses and their ability to be trained to detect a variety of medical issues/diseases are well known. Using their sense of smell, trained dogs can detect lung, breast, ovarian, bladder and prostate cancers. For prostate cancer, dogs had a 99 percent success rate in detecting the disease in patients simply by sniffing urine […]
What is a Molecular Property Spectrometer sensor?
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 […]
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 […]
What is the Air Quality Index? Pt 2
With over 90 forest fires raging along the West Coast, you may feel safe and think you do not need to check the air quality index (AQI) if you don’t live in that region. Think again! A recent satellite image shows that the smoke already extends all the way to Michigan. Don’t smell any smoke? […]
What is the Air Quality Index? Pt 1
Depending on where you live, your age, sensitivity to airborne constituents and other factors, the air quality index (AQI) could be something that you monitor frequently. In the U.S., the AQI developed by the Environmental Protection Agency (EPA) is a nationally uniform color-coded index for reporting air quality. Air agencies use the AQI report and […]
