Demonstrating Vibrational Current Generation With a Self‐Assembled Bioelectret

Advanced Functional Materials, EarlyView.
Vacuum‐deposited films of the plant‐derived molecule, Baicalein, form a self‐assembled bioelectret exhibiting spontaneous orientation polarization and a giant surface potential. The films induce alternating current during the vibration of a movable electrode without charging treatments. Hydrocarbon protection enhances the air stability of the Baicalein

Ultrawide Bandwidth Optomechanical Magnetometry Using Flux Concentration

Advanced Functional Materials, EarlyView.
High‐permeability flux concentrators enable ultrawide‐bandwidth chip‐scale optomechanical magnetometry by exploiting magnetic nonlinearity to up‐convert low‐frequency fields to the mechanical resonance, where sensitivity is optimal. This enables flat wideband operation over more than four orders of magnitude, from tens of kilohertz to sub‐hertz ...

A Thermodynamic Model of Antiferroelectics and Its Application to Electric Field Induced Antiferroelectric‐Ferroelectric Transition in PbZrO3

Advanced Functional Materials, EarlyView.
A thermodynamic model that incorporates ferroelectric, antiferroelectric, and antiferrodistortive orders of PbZrO3${\rm PbZrO}_3$ is established and parameterized based on experimental measurements and first‐principles calculations. We derive a Clapeyron‐like equation for describing the temperature‐dependence of critical electric fields for the ...
