Abstract: This paper presents a microelectromechanical-system (MEMS) piezoelectric pressure sensor for measurements in hypersonic flows at extreme temperatures (>1000 °C). Piezoelectric sensors are used for shock detection. This has largely been replaced by ceramics made from materials such as lead zirconate titanate (PZT) because of their larger piezoelectric effect. These ceramics have higher sensitivities than natural crystals. When a force is applied to a piezoelectric material, an electric charge is generated across the faces of the crystal. 481A_498ASeriesMultiChannelSignalConditioners,
