Abstract

"SENSOR DE CAPTAçãO SONORA". Um sensor (10) preferivelmente para uso em um estetoscópio eletrónico (15) compreende um corpo de transferência e contato viscoelástico de formato substancialmente cilíndrico (2) engatando de forma justa uma peça de suporte rígida (1) e sendo envolvida de forma justa por um membro piezelétrico, por exemplo, um ou dois ouropéis piezelétricos (4, 7) que convertem pressão sonora em sinais elétricos.
