title: Conductometric catheter-mounted pressure sensor.
abstract: We are developing an in vivo pressure sensor that measures the change in conductance of a deformable electrolyte-filled catheter resulting from external pressure. The sensor design and materials are easily scaled and inexpensive. The compact, in vivo nature of the device may result in the compact instrumentation being unobtrusively affixed to the patient externally and removing the tethered to an external apparatus, the current practice. We describe our initial device construction and in vitro pressure measurements.
