Abstract
Electroactive polymer transducers for sensory feedback applications are disclosed.
Claims13
A user interface device having sensory feedback comprising:
- a user contact surface;
- an electroactive polymer transducer comprising an output member coupled to the contact surface;
- a sensor for sensing a mechanical force on the user contact surface and providing an activation signal to the transducer,
- at least one pin extending between the output member and the user contact surface;
- a compliant material between the pin and the sealing material;
- and a scaling material adapted to substantially hermetically seal the transducer, wherein activation of the transducer moves at least a portion of the user contact surface, wherein the output member is mechanically coupled to the user contact surface, and wherein the at least one pin extends through the sealing material.
