Today’s cuff technique for measuring blood pressure (BP) goes back 100 years or so. While the sensors used to measure pressure have changed considerably, the inflate, deflate, and then-measure approach is quite similar. It has even been automated for home use. However, it is not a continuous measurement. In contrast, researchers are exploring several continuous, […]
What sensor accuracy is required?
While many parameters are used to determine the right sensor choice for a specific application, one of the most commonly required is accuracy. This single, seemingly straightforward term is easily understood but also frequently misunderstood, and is one way to determine whether a sensor technology or design meets the application requirements. Of course, many other […]
How do sensors reveal hidden aspects of the world’s oceans?
Oceans comprise about 96.5% of the water-covered surface (71%) of the Earth. Surprisingly, the salinity of these huge bodies of water varies considerably. Interconnected masses and layers mix together and split apart through currents, eddies, and changes to temperature and salinity, where salinity is measured in practical salinity units or PSUs. The Practical Salinity Scale 1978, […]
How are sensors in driver monitoring systems changing?
Government regulations, such as European Union (EU) General Safety Regulations and various New Car Assessment Programs (NCAP) requiring driver monitoring system (DMS) and the U.S. Federal Communications Commission (FCC) mandating child presence detection (CPD) systems in new cars, are incentivizing car makers and system suppliers to add more sophisticated sensors inside of new vehicles. The […]
How did sensing help identify the Las Vegas Tesla torcher?
As part of a global campaign targeting and seeking to punish Elon Musk for his involvement in DOGE (the Department of Government Efficiency), many people damaged Tesla vehicles, Tesla sales and service centers, and even Tesla public chargers. One of the more significant attacks occurred at a Las Vegas dealership where several (at least 5) […]
How can you make a sensor invisible?
Many sensors appear in plain sight, such as in cameras or home security systems’ presence/motion detectors. However, some are disguised in other products, such as a rearview mirror (camera) in a car or a smartphone. Specifically, the iPhone has 15 or more sensors embedded in its cell phone package design. Designers continue to find out-of-sight, […]
How does an electronic tongue sense: part 2
Part 1 showed two production techniques for electronic- or E-tongues. Researchers are busy investigating ways to use advanced artificial intelligence (AI) in conjunction with new sensing techniques to provide even more capabilities to E-tongues. Sensing for food problems To detect food fraud, spoilage, and contamination within minutes, researchers at Penn State University developed their version […]
How does an electronic tongue sense: part 1
When sensors that detect the five senses, hearing, sight, feeling, smell, and taste, are discussed, the one that usually gets mentioned the least is taste. Electronic ears, eyes, touch, and noses have far more available products than electronic tongues – but that could change. Like many sensors, the underlying technology for an electronic tongue (or […]
How does fusion timing impact sensors?
Today with LiDAR included as one of the potential sensing technologies, low-level fusion still seems to be a popular design approach.
What is a Ting sensor?
While the fires were still spreading in Los Angeles, investigators were busy exploring possible reasons for the fires and looking for indicators that could have provided more advanced warnings. Sensors always play an essential role in any advanced or real-time warning system. The more obvious sensor requirements/possibilities for wildfires include: Wind direction and speed Water […]
