  • Abstract
    A procedure for an electrical impedance characterization standard in air of CMUTs was reported. The electromechanical coupling factor was calculated by the low and high frequency capacity and the resonance and antiresonance frequencies measurements. The CMUT will be able to analyze and compared in terms of effective spring and mass with 1D model. The 1D model described the general behavior of the CMUT quite well, as long as first resonance/antiresonance mode and tensions below collapse were concerned
