[Curious Scientist] tried building an integrated strain gauge on a PCB, but ran into problems. Mainly, the low resistance of the traces didn’t show enough change under strain to measure easily. Even ...

Strain gauge sensors measure the strain (displacement) of an object under an applied force. When they are adhesively attached to the object under stress (an applied force), they deform with the object ...

When designing an experiment or test, simplicity is important. Each process added to a test or experiment to obtain data increases the potential for error. For ...

Before jumping into a discussion of amplifiers and signal-conditioning circuitry, it is worthwhile to quickly review strain gauges. By definition, “strain” is an alteration due to an external force. A ...

Strain—the response of a material to an applied stress due to an applied force or weight—is an important physical parameter in any application ranging from bridge monitoring to IC die packaging and ...

The levels of mechanicalstrain most typically measured with strain gauges are very small and precise.Consequently, changes in resistance are also very small and thus cannot bemeasured directly with an ...

Applied Measurements offer a complete design, bonding and wiring service from one-off projects to high volume applications. What’s more, we can even bond and wire onto your own free-issued hardware.

A knob can make a surprisingly versatile interface, particularly if it’s the SmartKnob, which builds a knob around a BLDC motor for programmable haptic response. It can rotate freely or with a set ...

Strain gage measurements are often plagued by offset drift, 1/f noise, and line noise. One solution is to use an ac signal to excite the bridge, as shown in Figure 1. The AD8221 gains the signal and ...
