Abstract

Displacement of a ceramic bimorph, due to the converse piezoelectric effect, has been observed using real-time, phase-stepped holographic interferometry. The observed bending obeys the theoretical solution. From the bending, the relevant piezoelectric constant was determined. The measured value, d₃₁ equals 279 +/- 9.5 pm/V, agrees with the commercial value of d₃₁ equals 274 +/- 55 pm/V. Displacement measurements for bone, however, were not repeatable. It appears that results for bone previously reported by us may have been experimental artifact.
