Recently, wearable pressure sensors have attracted tremendous attention because of their potential applications in monitoring physiological signals for human healthcare. Sensitivity and linearity are the two most essential parameters sensors. Although various designed micro/nanostructure morphologies been introduced, trade-off between sensitivity has not well balanced. Human skin, which contains force receptors a reticular layer, high even large external stimuli. Herein, inspired by skin...
The piezoelectric properties of lead zirconate titanate [Pb(Zr,Ti)O3 or PZT] ceramics could be enhanced by fabricating textured that would align the crystal grains along specific orientations. We present a seed-passivated texturing process to fabricate PZT using newly developed Ba(Zr,Ti)O3 microplatelet templates. This not only ensures template-induced grain growth in titanium-rich layers but also facilitates desired composition through interlayer diffusion zirconium and titanium....
Relaxor-lead titanate (PbTiO3) crystals, which exhibit extremely high piezoelectricity, are believed to possess electro-optic (EO) coefficients. However, the optical transparency of relaxor-PbTiO3 crystals is severely reduced as a result light scattering and reflection by domain walls, limiting applications. Through synergistic design ferroelectric phase, crystal orientation, poling technique, we successfully removed all light-scattering walls achieved an transmittance 99.6% in...
Perovskite multiferroics have drawn significant attention in the development of next-generation multifunctional electronic devices. However, majority existing exhibit ferroelectric and ferromagnetic orderings only at low temperatures. Although interface engineering complex oxide thin films has triggered many exotic room-temperature functionalities, desired coupling charge, spin, orbital lattice degrees freedom often imposes stringent requirements on deposition conditions, layer thickness...
Hydrogen is a promising fossil-fuel alternative fuel owing to its environmentally neutral emissions and high energy density.

This material was made piezoelectrically active by straightforward annealing process under different...
Conventional refrigeration methods based on compression-expansion cycles of greenhouse gases are environmentally threatening and cannot be miniaturized. Electrocaloric effects driven by electric fields especially well suited for implementation built-in cooling in portable electronic devices. However, most known electrocaloric materials present poor performances near room temperature, contain toxic substances, require high fields. Here, we show that lead-free ferroelectric thin-film bilayers...

Rare earth (RE) elements are the major component fabricating these PMs. Tremendous research interest has been generated over last decade to design RE-free PMs ever-increasing cost REs and shortage supply. Hexagonal ferrites show incredible potential as owing high coercivity moderate saturation magnetization. In this work, we focused on improving magnetic properties Sr 0.8 Ca...
Abstract Dielectric energy‐storage capacitors, known for their ultrafast discharge time and high‐power density, find widespread applications in pulse devices. However, ceramics featuring a tetragonal tungsten bronze structure (TTBs) have received limited attention due to lower capacity compared perovskite counterparts.

Flexible piezoelectric materials capable of withstanding large deformation play key roles in flexible electronics. Ferroelectric ceramics with a high coefficient are inherently brittle, whereas polar polymers exhibit low coefficient.

Single crystal or textured growth with preferred orientation of transition-metal oxide thin films is highly desirable for their application in technological devices. Commercially available single-crystal substrates are the obvious base to deposit a desired orientation. However, these have inherent shortcomings including limited number structures, lattice parameters and orientations, most importantly high costs.
