TEAR RESISTANT ELECTROACTIVE POLYMER TRANSDUCERS |
摘要 |
Described herein are several solutions that increase transducer lifetime by reducing or preventing tear propagation in a compliant electroactive polymer. One solution couples a compliant tear resistant treatment to a transducer proximate to an edge portion of the electroactive polymer. Another solution uses a tear resistant layer that couples to and covers a large surface area of the transducer. Another suitable tear resistant solution provides added material outside an active area; the added material reduces stress or strain variations in polymer material outside the active area when the electroactive polymer transducer is deflected or pre-strained
