摘要： An optical fiber sensor can be used to measure pressure with high sensitivity and fine resolution. As a cavity at the end of the sensor expands or contracts, the spectrum of a beam reflected from the end of fiber shifts, producing a change linked to pressure exerted on the sensor. Novel aspects of the present inventive sensor include the direct bonding of a silica thin film diaphragm to the optical fiber with localized or confined heating and a uniform thickness of the diaphragm. The resulting sensor has a diameter that matches the diameter of the optical fiber. Because the sensor is all silica, it does not suffer from temperature-induced error. In addition, the sensor can be very sensitive because the diaphragm can be very thin; it can also make highly repeatable measurements due to its very uniform thickness.

摘要： A system for measuring and indicating pressure that uses as its pressure sensing element an outer resilient tube, an inner resilient tube, and a rolling diaphragm connecting the inner and outer tubes, and held inside a protective enshrouding structure where pressure applied to the annulus between the tubes causes the diaphragm to deform and roll to axial extend the outer tube by an amount proportional to the applied pressure. The structure has features that enable visual correlation of the partially rolled tube's unrolled state with the applied pressure. The system can be incorporated into a syringe to create a pressure measuring syringe for inflating endotracheal cuffs while providing a reading of the cuff pressure.
