Abstract :
A new approach for the design and fabrication of a highly flexible blood pressure sensor is introduced in this paper. The goal is to measure the pressure within an aneurysm sac for post-endovascular aneurysms repair (EVAR) surveillance. Biocompatible polydimethylsiloxane (PDMS) membranes with embedded aligned carbon nanotubes (CNTs) are used to build the conductive elements of the pressure sensitive capacitor and the inductor for telemetry. Inductive coupling will be used to measure the internal capacitive variations. Fabricated test sensors validate the approach and demonstrate that CNTs/PDMS technology can be used to build highly flexible pressure sensors.
