Title (EN) ELECTROLUMINESCENT DEVICE
(FR) DISPOSITIF ÉLECTROLUMINESCENT
Abstract:
(EN) An example embodiment there is provided an electroluminescent device (10) comprising: an electroluminescent component (14), a first piezoelectric component (15), an alpha electrode (11 ) and a first beta electrode (12), the electroluminescent component (14) being located between the alpha electrode (11 ) and the first piezoelectric component (15), the first beta electrode (12) being in electrical contact with the alpha electrode (11 ) and in electrical contact with the first piezoelectric component (15), the alpha electrode (11 ), first beta electrode (12), first piezoelectric component (15), and electroluminescent component (14) being configured to generate a potential difference across the electroluminescent component (14) responsive to a mechanical stress applied to the first piezoelectric component (15).
(FR) L'invention concerne, selon un mode de réalisation, un dispositif électroluminescent (10), comprenant : un composant électroluminescent (14), un premier composant piézoélectrique (15), une électrode alpha (11) et une première électrode bêta (12), le composant électroluminescent (14) étant placé entre l'électrode alpha (11) et le premier composant piézoélectrique (15), la première électrode bêta (12) étant en contact électrique avec l'électrode alpha (11) et en contact électrique avec le premier composant piézoélectrique (15), l'électrode alpha (11), la première électrode bêta (12), le premier composant piézoélectrique (15) et le composant électroluminescent (14) étant conçus pour produire une différence de potentiel aux bornes du composant électroluminescent (14) en fonction d'une contrainte mécanique appliquée au premier composant piézoélectrique (15).
