Abstract

Un dispositif d'entrée a un corps d'entraînement ayant une unité de capteur, et une unité de production d'énergie ayant un élément piézoélectrique. Le corps d'entraînement coulisse dans une première direction en fonction d'une opération effectuée par un opérateur. Le corps d'entraînement forme également une partie ou la totalité d'un mécanisme permettant d'amener l'élément piézoélectrique à vibrer. Par conséquent, l'élément piézoélectrique vibre du fait du coulissement du corps d'entraînement dans la première direction, ce par quoi l'unité de production d'énergie produit de l'énergie. L'unité de capteur, utilisant l'énergie produite par l'unité de production d'énergie, détecte l'opération de l'opérateur et émet un signal de détection. Ceci permet au dispositif d'entrée de faire vibrer l'élément piézoélectrique avec une structure simple et de produire de l'énergie.
