Abstract
L'invention concerne un multiplexeur pour un appareil biométrique. Ce multiplexeur comprend une pluralité de premiers conducteurs couplés aux premières extrémités d'éléments piézocéramiques dans des rangées correspondantes, une pluralité de premiers commutateurs, chaque premier commutateur étant couplé à un premier conducteur respectif, et une pluralité de deuxièmes conducteurs couplés aux deuxièmes extrémités d'éléments piézocéramiques dans des colonnes correspondantes. Ledit multiplexeur comprend également une pluralité de deuxièmes commutateurs, chaque deuxième commutateur étant couplé à un deuxième conducteur respectif. Les premiers conducteurs sont à peu près perpendiculaires aux deuxièmes conducteurs, et les premiers commutateurs sont commandés pour coupler une sortie de signal provenant d'un port de sortie du générateur de signal à un élément piézocéramique particulier parmi au moins 25 000 éléments piézocéramiques. Les deuxièmes commutateurs sont commandés pour coupler un signal associé audit élément piézocéramique particulier parmi les 25 000 éléments piézocéramiques au moins à un port d'entrée du processeur.
