Abstract
Dispositivo de sensor de impressão digital inclui um substrato sensor, uma série de circuitos de sensor sobre uma primeira superfície do substrato sensor e uma camada transceptora localizada sobre a série de circuitos de sensor e a primeira superfície do substrato sensor. A camada transceptora inclui uma camada piezoelétrica e um eletrodo transceptor posicionado sobre a camada piezoelétrica. A camada piezoelétrica e o eletrodo transceptor são configurados para gerar uma ou mais ondas ultrassônicas ou para receber uma ou mais ondas ultrassônicas. O dispositivo sensor de impressões digitais pode incluir uma tampa acoplada ao substrato sensor e uma cavidade formada entre o revestimento e o substrato sensor. A cavidade e o substrato sensor podem formar uma barreira acústica.
