Flexomagnetic Effect in Wrinkled SrRuO3 Thin Films

Advanced Electronic Materials
The coupling between strain gradients and magnetic spins in perovskite thin films has long been a key focus of magnetism research, representing one of the essential pathways toward the realization of functional and flexible magnetic sensors and data ...

Flexoelectric MEMS

Piezoelectricity and flexoelectricity are two independent but not incompatible forms of electromechanical response exhibited by nanoscale ferroelectrics. Here, we show that flexoelectricity can either enhance or suppress the piezoelectric response of the cantilever depending on the ferroelectric polarity and lead to a diode-like asymmetric (two-state ...

Flexoelectricity in biomaterials

, 2018
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. De hecho, ya se ha observado en estereocilios del oído interno, apuntando a su importancia para la transducción acústico-eléctrica en la ...

Flexoelectricity versus Electrostatics in Polar Nematic Liquid Crystals [PDF]

Polar nematic liquid crystals have two special features, compared with conventional nematic liquid crystals. First, because of flexoelectricity, the combination of polar order and splay reduces the free energy.

Flexoelectricity and surface ferroelectricity of water ice

Frozen water at ambient pressure—common ice, also known as hexagonal Ih ice—is a non-polar material, even though individual water molecules are polar. Consequently, ice is not piezoelectric and cannot generate electricity under pressure.

Fracture toughening and toughness asymmetry induced by flexoelectricity

Cracks generate the largest strain gradients that any material can withstand. Flexoelectricity (coupling between strain gradient and polarization) must therefore play an important role in fracture physics. Here we use a self-consistent continuum model to
