"Optimising the thickness of the piezoceramic used within the stack of a Langevin transducer can be important [because] the thinner the piezoceramic element is, the better the electric field uniformity, the higher the effective electromechanical coupling coefficient and lower its impedance (higher the fow of current and hence amplitude for a given driving voltage). It is a common type of electromechanical transducer that can convert the rectilinear motion of an object to which it is coupled mechanically into a corresponding electrical signal. II) Electrical Transducers. A transducer emits an ultrasonic pulse and the time taken for the pulse to bounce off an object and come back is graphed in order to determine how far away the object is. Infrared radiation sources used in capnography must have high irradiance, uniform emissivity, large radiant area, and spectral uniformity. In this applications a piezoelectric disk is used to propagate a wave through liquid, with the goal of determining the density of the liquid from the time of flight.
