Abstract
a presente invenção se refere a um transdutor ultrassônico micromecânico piezoelétrico (pmut) que inclui um diafragma disposto sobre uma cavidade, o diafragma incluindo uma pilha de camadas piezoelétricas incluindo uma camada piezoelétrica, um primeiro eletrodo acoplado eletricamente com circuitos transceptores, e um segundo eletrodo acoplado eletricamente com os circuitos transceptores. o primeiro eletrodo pode estar disposto em uma primeira parte do diafragma, e o segundo eletrodo pode estar disposto em uma segunda parte, separada, do diafragma. cada um dos primeiro e segundo eletrodos é disposto sobre ou próximo a uma primeira superfície da camada piezoelétrica, a primeira superfície sendo oposta à cavidade. o pmut é configurado para transmitir primeiros sinais ultrassônicos por meio do primeiro eletrodo durante um primeiro período de tempo e para receber segundos sinais ultrassônicos por meio do segundo eletrodo durante um segundo período de tempo, o primeiro período de tempo e o segundo período de tempo sendo pelo menos parcialmente sobrepostos.
