Abstract

Electroactive polymer transducers for sensory feedback applications are disclosed.

Claims (18)

1. 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; and

a motion coupling mechanism extending between the user contact surface and the transducer,

wherein activation of the transducer moves at least a portion of the user contact surface and wherein the motion coupling mechanism comprises at least one pin.

2. 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; and

a motion coupling mechanism extending between the user contact surface and the transducer,

wherein activation of the transducer moves at least a portion of the user contact surface and wherein the motion coupling mechanism comprises a lever arm.

3. 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; and

a motion coupling mechanism extending between the user contact surface and the transducer,

wherein activation of the transducer moves at least a portion of the user contact surface and wherein the motion coupling mechanism is magnetic.

4. The user interface device of claim 1 , further comprising a sealing material between the transducer and the user contact surface.

5. The user interface device of claim 2 , further comprising a sealing material between the transducer and the user contact surface.

6. The user interface device of claim 3 , further comprising a sealing material between the transducer and the user contact surface.
