<p>A piezoelectric crystal element for use in force and pressure transducers and accelerometers, consisting of a monocrystalline cubic-polar material with electrode faces that intersect one of the crystallographic principal axes X,Y,Z at an angle alpha '=arc sin 2ROOT p and the other principal axes at beta '=+/-1/2 arc cos p, wherein p=0 for the piezoelectric orthoaxial shear effect, p=1/3 for the longitudinal piezoeffect and p=1 for the transverse piezoeffect.</p> |
