There is a slight difference between the static sensitivity and dynamic sensitivity.
Static Sensitivity. With the method of hanging weights (Figure 2(a)), the static response of the magnetostrictive whisker sensor is obtained and displayed in Figure 3.
From the diagram, we found that the curve is almost a straight line, meaning that the linearity of static sensitivity is good.
According to (4) and (5), the calculation value of static sensitivity [s.sub.s] is 2.20mV/mN.
