| 摘要 |
<p>The present invention is related to a method for manufacturing a laminar piezoelectric, piezostrictive respectively, transducer, either a sensor or an actuator, with in-plane variable apparent piezoelectric, piezostrictive respectively, coefficients (e31, e32), comprising a piezoelectric, piezostrictive respectively, sheet covered on at least one of its faces by an electrode made of a conductive layer, characterised in that said in-plane coefficients (e31, e32) variation is obtained through the patterning of the electrode, by providing said conductive layer with a plurality of internal non-conductive zones. <IMAGE></p> |
