Topologically Structured PLLA Fibers With Stress Concentration Effects for Health Monitoring
In this study, a multi‐path strategy was developed to enhance the piezoelectric properties of PLLA fibers through the stress concentration effect. The optimized devices generate piezoelectric output up to 14 times that of pure PLLA fibers. This piezoelectric enhancement strategy offers a new approach for high‐performance piezoelectric devices, with ...

Defect‐configurational origins of the asymmetric apparent electrostrain are revealed in different piezoelectric ceramics via atomic‐scale visualization of defect configurations. Migration of oxygen vacancies leads to the electrobending effect in N2‐sintered BaTiO3, while defect dipoles in Ba0.99TiO2.99 generate true asymmetric electrostrain without ...

Herein, we demonstrate a breakthrough in dielectric energy storage by engineering local polarization units in high‐entropy multilayer ceramic capacitors (MLCCs). The optimized MLCCs achieve an ultrahigh recoverable energy density of 18.2 J cm−3 with 91% efficiency, coupled with exceptional thermal stability and fatigue resistance.
