Abstract
An example embodiment there is provided an electroluminescent device comprising: an electroluminescent component, a first piezoelectric component, an alpha electrode and a first beta electrode, the electroluminescent component being located between the alpha electrode and the first piezoelectric component, the first beta electrode being in electrical contact with the alpha electrode and in electrical contact with the first piezoelectric component, the alpha electrode, first beta electrode, first piezoelectric component, and electroluminescent component being configured to generate a potential difference across the electroluminescent component responsive to a mechanical stress applied to the first piezoelectric component.
