Bill Schweber A wearable millimeter-sized accelerometer functions as a microphone to capture the vibrations created by heart and lung functions, thus providing additional physiological data. Electronics for “personal” medical devices is ...

Chris Petrich github.com A test purchase of 1,000 sensors from 70 different sellers showed the majority to be counterfeits of extremely variable performance. ...unless you bought the chips directly from Maxim Integrated (or Dallas Semiconductor in ...

Helmholtz-Zentrum Dresden-Rossendorf HZDR researchers use sensors to give humans magnetoception While birds are able to naturally perceive the Earth’s magnetic field and use it for orientation, humans have so far not come close to replicate ...

Ian Beavers, Analog Devices Analog Dialogue Question: I have heard that it is possible for a gyroscope heading to accumulate drift error over time. Can this happen in my IMU? Answer: A MEMS gyroscope, which measures angular rate, has several ...

By Tom Lecklider Evaluation Engineering Most electronic engineers know that a transistor's base-emitter voltage (V BE ) has a temperature coefficient (TC) of about 2 mV/ C. However, for precision temperature sensors, about isn't good ...

Mitchell Lee, Linear Technology LT Journal of Analog Innovation The LTC2983 solves the unique problems presented by all standard temperature sensors to produce unmatched conformity and ease-of-use. Temperature measurement is not new. Galileo ...

By Ken Kingery Duke University A new sensor developed at Duke University helps computers separate overlapping sounds. People trying to talk to Siri may soon no longer have to look like they’re about to eat their iPhones, thanks to a new ...

Tekla S. Perry IEEE Spectrum The Biostamp can replace today's clunky biomedical sensors I turn the key to start the little Ford SUV I’ve rented for my visit to the University of Illinois at Urbana-Champaign, and a message flashes briefly on ...

Tekla S. Perry IEEE Spectrum Part 1 Right now, Rogers and his students are evaluating stretchable sensors that measure body temperature, monitor exposure to ultraviolet light, and check pulse and blood-oxygen levels. They’re also developing ...

Ken Wada embedded.com Temperature is one of the most common parameters monitored by an embedded system. There is a wide array of temperature sensors available to achieve this. The sensor types can range from exotic black body detectors to the ...
