Abstract: An implantable pressure sensor arrangement is disclosed. The arrangement includes a substrate, a coil positioned on the substrate, a flexible membrane positioned proximate to the coil and configured to be moveable with respect to the coil, thereby forming a fluid chamber, fluidly sealed from outside of the implantable pressure sensor arrangement, a porous membrane positioned on the flexible membrane and configured to transfer pressure from outside of the implantable pressure sensor arrangement onto the flexible membrane wherein a differential pressure is generated on the two sides of the flexible membrane thereby causing the flexible membrane to deflect towards and away from the coil, and an electrode coupled to the flexible membrane.
