摘要：

A new, powerful and sensitive pressure sensor has been developed to detect deformations of a magnetic fluid (MF) membrane. The output voltage is a linear function of the differential pressure experienced by the MF membrane, which acts as a safety valve beyond some breaking conditions. Increasing or decreasing the pressure leads to reproducible measurements with no hysteresis.
