Competing anticlastic and piezoelectric deformation at large deflections
Salmani, Hamed; Hanke, Ulrik; Halvorsen, Einar (Peer reviewed; Journal article, 2021)In bending of a purely elastic beam or plate, it is well established that the cross-sectional shape changes character with decreasing bending radius-of-curvature and that the transition can be characterized by the Searle ... -
Electrode Design Based on Strain Mode Shapes for Configurable PMUTs
Mansoori, Amirfereydoon; Hoff, Lars; Salmani, Hamed; Halvorsen, Einar (Peer reviewed; Journal article, 2023)Piezoelectric micromachined ultrasonic transducers (PMUTs) with multiple electrodes can be utilized as multi-frequency transducers by exciting selected vibration modes of the diaphragm providing configurability that may ... -
Modal analysis of piezoelectrically actuated plates with built-in stress by computationally augmented interferometric experiments
Salmani, Hamed; Bodo, Elisabetta; Hanke, Ulrik; Vogl, Andreas; Jain, Shruti; Merlo, Sabina; Halvorsen, Einar (Peer reviewed; Journal article, 2022)The conventional laser doppler vibrometers for modal analysis of micro-structures are expensive and sometimes inaccessible. In this work, a compact, fiber-based interferometric setup is used to carry out the modal analysis ...
