複合物圧電アクチュエータを用いた触覚フィードバック

摘要

The present invention provides an electronic device comprising a touch sensitive layer configured to sense if an object touches the touch sensitive layer and to sense where the touch sensitive layer is contacted; a display layer configured to visually display images; a composite piezoelectric assembly that is substantially planar and has a cut-out so that the composite piezoelectric assembly forms a frame around the touch sensitive layer and forms a seal with the touch sensitive layer to protect the display layer, wherein the composite piezoelectric assembly comprises a first electrode layer, a second electrode layer, and a composite piezoelectric layer between the first electrode layer and the second electrode layer, and a drive circuit configured to apply an alternating voltage to the first electrode layer and the second electrode layer
