Beschreibung
Zusammenfassung:	An ultrasonic transmitter and ultrasonic receiver include a piezoelectric layer and at least one conductive layer comprising metal nanoparticles. The metal nanoparticles may be a silver nanoparticle, copper nanoparticle, gold nanoparticle, palladium nanoparticle, nickel nanoparticle, and the mixture thereof. Use of metal nanoparticles as a conductive layer provides for ultrasonic transmitters or receivers with smooth, dense, and highly conductive electrodes, thus resulting in reduced ultrasonic energy loss and improved image quality.
