Most medical ultrasound transducers are piezoelectric. Commonly, piezoelectric ultrasound transducers are employed. Ultrasonics, typically refers to piezoelectric transducers or capacitive transducers. Hall effect sensors with linear transducers are commonly integrated with digital electronics. Lead zirconate titanate-based materials are components of ultrasound transducers and ceramic capacitors, STM/AFM actuators (tubes). The pressure differential is typically measured using diaphragm pressure transducers with digital readout. It is a piezoelectric material used in microphones and other transducers. This can be done using piezoelectric transducers. In electronic engineering, actuators are a subdivision of transducers. Many types of sensors are used, including strain transducers, accelerometers, tiltmeters, and GPS. This limits their use in applications such as sensors, detectors and transducers. It is used in capacitors, electromechanical transducers and nonlinear optics. Mineralization of the ultrasonic transducers requires maintenance and potential for component failure. Engineers in the field are developing products like intelligent sensors, smart transducers, and microelectromechanical systems. Bending wave transducers use a diaphragm that is intentionally flexible.
