  • Abstract
    Test structures for piezoelectric micromachined ultrasonic transducers have been fabricated and investigated. The basic element consisted of a silicon membrane coated with a 2 μm thick (100)-textured Pb(Zr,Ti)O3 (PZT) thin film deposited by sol-gel techniques. SOI wavers have been applied to obtain a good definition of the silicon part of the membrane. Test devices have been characterized in air and in an insulating liquid.
