Determinação de coeficientes piezoelétricos pela aplicação do novo método diferencial interferométrico

Abstract in Portuguese
Utilizando o Interferômetro Fabry-Perot desenvolveu-se um novo método interferométrico capaz de detectar variações de comprimento com precisão da ordem de angstroms. Aplicando o referido método determinou-se alguns coeficientes piezoelétricos através do efeito piezoelétrico inverso. A grandeza dos coeficientes em 10-12m/V encontrados foram: em osso d12 = 0,05; d13 = 0,07; d14 = 0,23, em colágeno (osso descalcificado) d13 = 0,15; d14 = 0,98 e finalmente em colágeno nativo (tendão de Aquilles) d13 = 0,17 ; d14 = 1,75

Abstract in English
Utilizing a "Fabry-Perto Interferometer" a new interferometric method has been developed, capable of detecting lenght variations with a precision of a few Angstrons. Determinations mande by this method of the inverse piezoelectric effect , show the following results in 10-12m/V: for bone d12 = 0,05; d13 = 0,07; d14 = 0,23, collagen (decalcified bone) d13 = 0,15; d14 = 0,98 and for native collagen (Achilles tendon) d13 = 0,17 ; d14 = 1,75.
