A strain gauge extensometer is a device used to measure the deformation (strain) of an object under stress. It consists of a strain gauge, which is a sensor that detects changes in resistance due to deformation, and a mechanical structure that ensures accurate placement on the test specimen. Extensometers are commonly used in materials testing to monitor how materials respond to applied forces, providing critical data for engineering and research applications. Their precise measurements help in assessing material properties and structural integrity.

What is principle of strain gauge?
change in temperature causes change in pressure
How strain gauges detect touch?
Strain gauges detect touch by measuring the deformation or strain in a material when force is applied. When a person touches the surface, the strain gauge experiences a change in resistance due to the bending or stretching of its material. This change in electrical resistance is then converted into a measurable signal, indicating the presence and magnitude of the touch. This technology is commonly used in touch-sensitive applications like touchscreens and pressure-sensitive devices.
Difference betwwen bounded and unbounded strain gauge?
Bounded strain gauges are designed to operate within a specific range of strain, providing accurate measurements only within that limit, while unbounded strain gauges can theoretically measure strain without a predefined limit, allowing for broader applications. Bounded gauges typically feature a protective element that restricts their range, ensuring reliability and precision under controlled conditions. In contrast, unbounded strain gauges may be used in scenarios where extreme strains are expected, though they may sacrifice some accuracy and stability. The choice between the two depends on the application requirements and the expected strain conditions.
What are passive transducers and examples?
Passive transducers are the transducers which requires an external power supply to operate and the output is a measure of some variation in passive components. Example- Differential transformers, Resistance strain gauge etc..

What is difference between strain gauge and extensometer?
Strain gage and Extensometer both are same purpose to check the stress and strain in selective test pieces, but traditional they were using strain gage its take the preparation time is high and Extensometer we are check the directly both results are same.

How youngs modulus is determined?
A standard specimen is loaded on a tensile test machine; load,P, is applied and measured with a load cell and strain, e, is measured with a strain gauge extensometer. In the linear region, load is divided by specimen area to get stress, s, and the modulus, E, is determined from Hooke's law, where E = s/e

The advantage of a semiconductor strain gauge over the normal strain gauge is that?

How do you increase the sensitivity of a force sensor using strain gauge?
You can increase the sensitivity of a force sensor using a strain gauge by either increasing the gauge factor (by using materials with higher sensitivity to strain) or by increasing the strain applied to the gauge (by increasing the length or width of the gauge). Both methods will increase the change in resistance of the strain gauge in response to applied force, resulting in higher sensitivity.
