Introduction
A resistive strain gauge sensor with a 350-ohm nominal resistance which varies when
a force is applied. By measuring the change in the sensor's resistance, a
measurement of the force applied to it can be obtained. The strain gauges exhibit
small changes in resistance. Usually used in general metal materials and other similar
elastomers.
