In this paper, the mass sensitivity of a 3-Dimensional SiO2/36°YX LiTaO3 Love mode SAW biosensor is investigated by a novel approach. The normalized displacement confirms the shear horizontal nature of Love wave. The phase mass sensitivity of 76.4931 m2/kg is obtained by evaluating the phase shifts. The insertion loss of -17.2dB is achieved by impulse response analysis. This Love mode SAW biosensor has potential applications in detecting viruses, cancer markers, bacteria, etc.
