Giant Piezoelectric Output and Stability Enhancement in Piezopolymer Composites with Liquid Metal Nanofillers

“…Additionally, the impressive high d 33 value and output voltage in this work also benefit from the local electric field stemming from GaIn conductive filler that further improves the polarizability and corresponding piezoelectric property of GaIn NDs/PVDF‐TrFE composite membrane. [ 27 ]…”

Giant piezoresponse in nanoporous (Ba,Ca)(Ti,Zr)O3 thin film

“…Our nanoporous BCZT lm demonstrates signicant piezoelectricity solely through the introduction of a nanoporous structure, eliminating the necessity for creating intricate architectures, such as nanowires, nanobers, or nanocore/shell structures. [26][27][28] This study introduces a new approach for the cost-effective production of Pb-free piezoelectric materials using much lower annealing temperatures while achieving an ultra-high piezoresponse, d 33 . Furthermore, it opens up a new avenue for high-density energy harvesting applications, serving as a renewable alternative to fossil fuelsan aspect that has not previously been explored.…”

Polyvinylidene Fluoride Based Piezoelectric Composites with Strong Interfacial Adhesion via Click Chemistry for Self‐Powered Flexible Sensors

“…Meanwhile, the deformation caused by external forces acting on the object is regarded as elastic strain under bending conditions. [26] Thus, polarized BT fillers can generate relevant stress and electric potential under the impact of external forces (Figure 6a,b). To understand the stress and potential distribution more intuitively, it is observed from the linear diagram extracted along the 2D central section (Figure S23, Supporting Information), as revealed by Figure 6c,d.…”
