A strain gauge is used to measure the strain on an object. It is a very thin, flat coil of conductive wire. (Editor's note: strain “gauge” is often spelled as “gage”; why this is so, and which is ...

We are always impressed with something so simple can actually be so complex. For example, what would you think goes into an analog computer? Of course, a “real” analog computer has opamps that can do ...

The use of two active strain-gauge elements in a half-bridge configuration enhances bending-strain measurement sensitivity.

What are signal-conditioning aspects for amplifiers that design engineers must grasp for precision applications? What are the design considerations for selecting and implementing a signal-conditioning ...

Sometimes the simplest hacks can be the most useful or ingenious, and such is the case with [Keri Szafir]’s method of ensuring that potentiometers used in audio devices are matched. If you consider a ...
