Pressure sensing apparatus including a plurality of electroactive polymer strips

One or more electroactive polymer (EAP) strips are circumferentially or lengthwise embedded or mounted around the fluid passage member. The EAP strips change electrical characteristics (e.g., capacitance, resistance) independent of an applied actuation as they are stretched, so they may be used to m...

More Information
Summary:One or more electroactive polymer (EAP) strips are circumferentially or lengthwise embedded or mounted around the fluid passage member. The EAP strips change electrical characteristics (e.g., capacitance, resistance) independent of an applied actuation as they are stretched, so they may be used to measure fluid pressure and/or fluid flow rate.
