to the sensor. Because each friction driven piezoelectric actuator can provides 12Newton force, the insertion trans-lational motion is provided by two linear motors. In terms of the insertion force range, 10Newton interaction force is the maximum required for each sensor. The finite element analysis in Fig. 6 illustrates the maximum strain 100μ under 10 Newton axial force using ABS plastic material with a Young’s Modulus of 2GP a and Poisson’s ratio 0.34.
