Abstract

Patente de Invenção: <B>"DISPOSIçãO DESLOCADA DE ELETRODOS EM UM TRANSDUTOR PIEZOELéTRICO"<D>. Um transdutor compreende um membro piezelétrico (29) que deforma em uso para prover uma saída elétrica, e primeiro e segundo eletrodos (22, 26) dispostos nos lados opostos do membro piezoelétrico para colher a saída elétrica. Os eletrodos (22, 26) são deslocados de forma a prover uma ou mais regiões nas quais os eletrodos (22, 26) não se sobrepõem. Um ou mais eletrodos (22, 26) podem ser descontínuos e podem compreender uma pluraridade de dedos. O membro piezoelétrico (29) pode ser na forma de uma chapa.
