Abstract
There is provided a touch sensitive element including an electroactive layer, and an electrode disposed on at least one surface of the electroactive layer. The electroactive layer has a first portion having a first thickness and a second portion which has a second thickness different from the first thickness and is in contact with the first portion at an outside of the first portion.
Claims28
A touch sensitive element, comprising:
- an electroactive layer comprising a first portion of a first thickness and a second portion of a second thickness that is greater than the first thickness;
- a first electrode electrically coupled to a surface of the electroactive layer;
- and
- a second electrode electrically coupled to a same surface or a different surface of the electroactive layer as the first electrode, the electroactive layer configured to vibrate responsive to applying a voltage difference between the second electrode and the first electrode.
