Piezoelectric bimorph actuation has been successfully used in numerous types of microdevices, most notably micropumps. However, even for the simple case of circular geometry, analytical treatments are severely limited. This study utilized the finite-element method to optimize the deflection of a circular bimorph consisting of a single piezoelectric actuator, bonding material and elastic plate o...
Abstract Beams, plates, and shells, as the fundamental mechanical structures, are widely used in microelectromechanical systems (MEMS) nanoelectromechanical (NEMS) sensors, actuators, energy harvesters, among others. Deeply understand electromechanical coupling of these dielectric structures is crucial for designing, fabricating, optimizing practice devices systems. Herein we demonstrate flexoe...
Leak localization is essential for the safety and maintenance of storage vessels. This study proposes a novel circular acoustic emission sensor array to realize the continuous CO₂ leak localization from a circular hole on the surface of a large storage vessel in a carbon capture and storage system. Advantages of the proposed array are analyzed and compared with the common sparse arrays. Experim...
