We first revisit the mathematical modeling of flexoelectric effect in context continuum mechanics at infinitesimal deformations. establish and clarify relation between different formulations, point out theoretical numerical issues related to resulting boundary value problems, present natural extension finite then a simple B-spline based computational technique numerically solve associated which...

The ability of certain materials to convert electrical stimuli into mechanical deformation, and vice versa, is a prized property. Not surprisingly, applications of such so-called piezoelectric materials are broad—ranging from energy harvesting to self-powered sensors. In this perspective, written in the form of question-answers, we highlight a relatively understudied electromechanical coupling ...

The piezoelectric properties of bone play an important role in the bone remodeling process and can be employed in clinical bone repair. In this study, the piezo-voltage of bone between two surfaces of a bone beam under bending deformation was measured using an ultra-high-input impedance bioamplifier. The influence of shear stress on the signs of piezo-voltages in bone was determined by comparin...

Stimulated by state-of-the-art robotic and computer technology, Intra Cytoplasmic Sperm Injection (ICSI) automation aims to scale and seamlessly transfer the human hand movements into more precise and fast movements of the micro manipulator. Piezo-drill cell injection, a novel technique using piezo-driven pipettes with a very small mercury column, has significantly improves the survival rates o...

Through the suitable geometry of a repeating unit, metamaterial can exhibit property not present in base material. Here, we propose class low area-fraction, bending-dominated metamaterials that apparent piezoelectricity, even though material is piezoelectric. The proposed exploit universal electromechanical coupling operative at sub-micron scales, flexoelectricity, and upscale it to macro-scale...
