This paper presents low power circuit design for voltage regulator and resistor to digital converter that are used in a RFID-like sensing circuit for measuring the resistance of a sol-gel sensor. The ...

I would approach the RFID reader using a variation on this circuit; a single transistor regenerative receiver which is just oscillating at 125 kHz, but whose oscillation is quenched momentarily ...

There are numerous applications for low-cost materials sensing; however most RFID sensing solutions are limited to measurement of permittivity. To address this need, we present a novel materials ...

Alternatively, Farsens is one company that has already developed passive sensing tags (see Spanish Startup Focuses on Passive RFID Sensors for Manufacturing and Other Industries); however, Farsens’ ...

MIT engineers configure RFID tags to work as sensors. The new platform may enable continuous, low-cost, reliable devices that detect chemicals in the environment.

Unlike conventional digital sensors, which depend on complex circuits and converters, this method simplifies data capture and minimizes power requirements. The team wondered whether they could ...

Security is alerted when an asset is moved by unauthorized personnel. The motion sensor complements other RFID tags in the Axcess ActiveTag line. The company offers battery-powered RFID tags that are ...

Schmersal has applied Radio-frequency identification (RFID) technology in the new RSS36 series non-contact safety sensor. The RSS36 is designed for application in safety circuits monitoring the ...

Sensors and automatic identification have already transformed supply chains. RFID tags and scanners, barcodes, QR codes, and handheld or fixed position scanners and imagers generate real-time data ...
