Abstract This article discusses the applications of an operational amplifier for electrochemical gas sensors such as ethanol and carbon monoxide (CO). It also discusses the desired performance to provide optimum results for accurate measurement of ...

Sensors such as strain gages, RTDs (resistance temperature detectors), and thermistors produce a resistance that’s proportional to force or temperature. If you measure a sensor’s resistance, you can calculate the physical parameter. ...

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 an area of ...

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 ...

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 internal contributors to error, ...

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 ...

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 invented a rudimentary thermometer capable of detecting temperature ...

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 ...
