The characterization of the first in-plane mode of AlN-actuated piezoelectric microcantilevers was done using different techniques. The top electrode of the cantilever was designed to allow for an efficient electrical actuation of these in-plane modes. The detection of the electrically induced in-plane movement was performed optically with the help of a stroboscopic microscope and electrically by means of an impedance analyzer. The quality factor and the resonant frequencies of the in-plane modes were estimated from the above techniques. Our results show quality factor values as high as 3000 for the first in-plane mode in air.
