Graphene-based flowmeter sensor measures nano-rate fluid flows, Part 1: The challenge
When it comes to nearly all biological measurements, the ranges of many of the parameters of interest are orders-of-magnitude below those with which many engineers are familiar. Instead of megahertz or even kilohertz, the living-creature world is in the single or double-digit hertz range, such as the roughly 60+ beats per minute (BPM) for a […]
What are the different types of fingerprint scanners?
Fingerprint scanners, which were once reserved for biometric logging systems and attendance systems, are now part of regular smartphones and much more. Fingerprints have been a trusted method of personal identity. Combined with face id or other biometric identification systems like retina scanning, fingerprints offer an impeccable way to recognize any person. With a blast […]
Using optical fibers for temperature measurement, Part 3: Variations
Among the many ways to sense temperature, combinations of advanced optical principles used with optical fibers offer very different approaches, with application advantages and implementation limitations. The previous part of this article looked at two approaches to using optical fibers for temperature sensing based on the fiber Bragg grating (FBG) and the Mach-Zehnder interferometer (MZI). […]
Analyzing different proximity sensor technologies
Utilized as a no-touch method to provide either precise distance measurement to an object or simple “there/not there” logic, proximity sensors span a wide range of technologies, each offering their own set of operating principles, advantages, and drawbacks. Some of the most commonly found technologies in portable or small embedded systems include ultrasonic, photoelectric, laser […]
Calibrated and ISO 17025-certified sensors for drugs and perishable goods transportation
Sensirion has announced its new calibrated and ISO 17025-certified humidity and temperature sensors. These sensors enable customers to achieve cost-efficient GDP-compliant supply chain monitoring of drugs, vaccines, and perishable goods. Highly regulated products, such as pharmaceutical or perishable goods, typically require special handling along their distribution chain to comply with several directives. Manufacturers are obligated […]

Shot camera, sensor development kits get middleware support for global public clouds
ON Semiconductor has announced that the RSL10 Smart Shot Camera and the RSL10 Sensor Development Kit have been pre-integrated within the Bosch IoT Suite, the Bosch Group’s core software platform and core software ecosystem for the Internet of Things (IoT). The RSL10 Smart Shot Camera and the RSL10 Sensor Development Kit are complete node-to-cloud solutions […]
4-in-1 MEMS sensor measures gases, humidity, temperature and barometric pressure
Whether at home, in the office, or outdoors, we need to be confident that the air around us is clean and safe to breathe – COVID-19 has clearly highlighted the importance of air quality. Due to the particulates, gases, and even airborne viruses ubiquitously present in our modern environment, poor air quality has an increasingly […]
