5 p, 445.5 KB Piezoelectric Mimicry of Flexoelectricity / Abdollahi, Amir (Universitat Politècnica de Catalunya) ; Vásquez Sancho, Fabián (Institut Català de Nanociència i Nanotecnologia) ; Catalan, Gustau (Institut Català de Nanociència i Nanotecnologia)
The origin of "giant" flexoelectricity, orders of magnitude larger than theoretically predicted, yet frequently observed, is under intense scrutiny. There is mounting evidence correlating giant flexoelectriclike effects with parasitic piezoelectricity, but it is not clear how piezoelectricity (polarization generated by strain) manages to imitate flexoelectricity (polarization generated by strain gradient) in typical beam-bending experiments, since in a bent beam the net strain is zero.

10 p, 3.8 MB Investigation of The Cellular Response to Bone Fractures : Evidence for Flexoelectricity / Núñez Toldrà, Raquel (Institut Català de Nanociència i Nanotecnologia) ; Vásquez Sancho, Fabián (Institut Català de Nanociència i Nanotecnologia) ; Barroca, Nathalie (Institut Català de Nanociència i Nanotecnologia) ; Catalan, Gustau (Institut Català de Nanociència i Nanotecnologia)
The recent discovery of bone flexoelectricity (strain-gradient-induced electrical polarization) suggests that flexoelectricity could have physiological effects in bones, and specifically near bone fractures, where flexoelectricity is theoretically highest. [...]

14 p, 1.0 MB Flexoelectricity in bones / Vásquez Sancho, Fabián (Institut Català de Nanociència i Nanotecnologia) ; Abdollahi, Amir (Universitat Politècnica de Catalunya. Laboratori de Càlcul Numèric) ; Damjanovic, Dragan (Ecole Politechnique Federale de Lausanne) ; Catalan, Gustau (Institut Català de Nanociència i Nanotecnologia)
Bones generate electricity under pressure, and this electromechanical behavior is thought to be essential for bone's self-repair and remodeling properties. The origin of this response is attributed to the piezoelectricity of collagen, which is the main structural protein of bones. [...]

129 p, 3.7 MB Flexoelectricity in biomaterials / Vásquez Sancho, Fabián ; Catalan Bernabé, Gustau, dir. ; Sort Viñas, Jordi, dir. ; Universitat Autònoma de Barcelona. Departament de Física ; Institut Català de Nanociència i Nanotecnologia (ICN2)
La flexoelectricidad es la capacidad de los materiales para generar electricidad al deformarse de forma no homogénea. Es una propiedad de todos los materiales y, en principio, posible que existiera en biomateriales. [...]
Flexoelectricity is the ability of materials to generate electricity upon being bent, or, more generally, upon being inhomogeneously deformed. It is a property that is allowed by symmetry in all materials and, therefore, it was in principle possible that it existed in biomaterials -one precedent existed for their observation in inner-ear stereocilia, in fact, pointing to its importance for acousto-electric transduction in mammalian hearing.
