Abstract
A sensor including a buffer material layer configured to at least partially deflect when a force or pressure is imparted on the buffer material layer; and an electroactive polymer (EAP) cartridge in operative contact with the buffer material layer, wherein the EAP cartridge is configured to generate an output signal that corresponds to an amount of strain imparted on the EAP cartridge. The EAP cartridge may be used in a variety of sensing applications including as a pressure sensor integrated into a fluid connector. One aspect of the invention provides for selection of a buffer material layer based upon a desired pressure range.
