| Abstract: | The orthotropic mechanical sensing unit is presented which is made from piezoele ctric composite material. It is capable of detecting the surface stresses of bot h isotropic and orthotropic material structure. The sensing equations of the sen sing units are deduced. The dynamic and static properties of the OPCM units are calibrated and its advantages are proved. |
