What are the seven types of quantum sensors?
The seven types of quantum sensors include chemical sensors, clocks, gravimeters, imaging, interferometers, magnetometers, and thermometers. Several types of quantum sensors are already in use, and more are being developed for commercialization. They can be used in a wide variety of applications from earth sciences to molecular biology and wide band gap power semiconductors. Chemical […]
What technologies are used to make quantum sensors?
Quantum sensors rely on quantum mechanical principles like entanglement, interference (also called superposition), discrete quantum states, and coherence. They are unlike quantum computers, which need highly stable environments for operation. Some quantum sensors can operate at room temperature. As a result, quantum computers are still a work in progress, while quantum sensors are used today. […]
How is sensor fusion used in medicine?
Sensor fusion is most frequently discussed in smartphone and automotive control applications. However, the fusion aspect was initially created for military analysis. From the analysis standpoint, for improved decision-making, medical applications can and have benefited from sensor fusion. One example is in cancer detection and focused surgery. Specifically, the detection of and surgery for prostate […]
How do diffuse, retroreflective, and through-beam ultrasonic sensors differ?
Ultrasonic frequencies are above the human audio range – higher than 20 kHz. Operating in the ultrasonic frequency range, ultrasonic sensors are commonly used for measuring proximity (distance), determining the level in storage tanks, detecting objects, and more. By measuring the time it takes for sound to travel to and reflect off the surface (time […]
How will sensors be used to increase warehouse automation?
Many of today’s warehouses have been or are in the process of transitioning from strictly a manual or conventional warehouse to a partially and eventually a fully automated warehouse. Depending on the level of sophistication, any automated process requires a variety of sensing technologies. Research from one company predicts that over 75% of companies will […]
What sensors are used to monitor volcanoes?
Monitoring volcanoes is complex, and it’s an important activity to ensure public safety in many areas of the world. It involves monitoring ground deformations, earthquakes and vibrations, volcanic gas, rock and water chemistry, and remote sensing from satellites. Volcano monitoring needs to be implemented on a continuous basis or in near-real-time and is an extreme […]
How do micro photo sensors work and what are they used for?
Micro photo sensors have built-in amplifiers and are available in a variety of configurations, with modulated, non-modulated, and polarized light beams. They’re used to provide precise and stable sensing or positioning of materials, components, or assemblies. Some have integrated connectivity, like IO-Link and IP 67 environmental ratings. Uses for micro photo sensors include precision manufacturing […]
What is normal blood pressure?
If you answered 120 over 80 mmHg, you are using criteria that is over 20 years old. As reported in a 2003 article, revised guidelines categorized normal blood pressure as <120/80 mmHg. Since the measurements are meant to lower the risks from not recognizing what is often called the silent killer – high blood pressure […]
What are the key specifications of machine vision sensors?
Charged coupled devices (CCDs) and CMOS active pixel sensors (CMOS sensors) are the primary image sensor technologies. They rely on lenses and other optical components to deliver the image to be captured. This FAQ reviews the differences between CCDs and CMOS sensors, looks at some key specifications of image sensors and the concept of quantum […]
