Abstract

Actuador piezoeléctrico, que comprende una lámina de base metálica (1), que incluye una parte de banda (3) definida por dos cortes paralelos (2) practicados en la lámina de base (1), estando dicha parte de banda deformada separándose del plano de la lámina de base (1) con el fin de adoptar una configuración de tejado, con dos partes inclinadas (4, 5) que convergen hacia un ápice común (6) a partir de la lámina de base (1), comprendiendo además dicho actuador piezoeléctrico una capa piezoeléctrica que cubre la lámina de base (1) y las dos partes inclinadas (4, 5), dos electrodos (10, 11) aplicados sobre dichas dos partes inclinadas (4, 5), y medios de suministro eléctrico (12) adaptados para aplicar separadamente un voltaje eléctrico a dichos electrodos (10, 11).
