Patent ID: 8513883

Claim:
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, wherein the alpha electrode, first beta electrode, first piezoelectric component, and electroluminescent component are configured to generate a potential difference across the electroluminescent component responsive to a mechanical stress applied to the first piezoelectric component, and further comprising: a second piezoelectric component, and a second beta electrode that is in electrical contact with the alpha electrode and in electrical contact with the second piezoelectric component, the electroluminescent component being located between the alpha electrode and the second piezoelectric component, wherein the electroluminescent component, the alpha electrode, the second beta electrode, and the second piezoelectric component are configured to generate a potential difference across the electroluminescent component responsive to a mechanical stress applied to the second piezoelectric component and wherein the second beta electrode is located between the alpha electrode and the first beta electrode.
