Abstract
An apparatus includes an electroactive polymer member and a first electric terminal and a second electric terminal. The electroactive polymer member has a free portion configured to change position relative to a fixed portion in response to an external stimulus corresponding to at least one of a flow parameter or a fluid parameter. The first electric terminal and the second electric terminal are coupled to the electroactive polymer member. The first electric terminal and the second electric terminal provide an electrical signal in response to the change.
