Application of capacitive transducer Capacitive type transducers has wide range of applications in which s0me of them are: In Microphones In Semiconductor Industries In Detecting Dynamic Motion 8. So, in the capacitive transducer, the change in the capacitance is used to measure the physical quantities. High-performance flexible pressure sensors are highly desirable in health monitoring, robotic tactile, and artificial intelligence. expansion. Costs, while of-ten thought to be higher, are actually extremely competitive in quantity. A capacitive transducer was developed to measure blood pressure using a catheter interfaced to the body.
