Harnessing Outer Space for Improved Electrocaloric Cooling

Advanced Functional Materials, Volume 36, Issue 6, 19 January 2026.
A novel radiative heat sink/source‐integrated electrocaloric (R‐iEC) system combines the electrocaloric (EC) effect with a thermally conductive radiative cooler (TCRC) to address heat dissipation limitations in EC devices. Utilizing outer space as a heat sink, the system achieves up to 240 W m−2 of heat dissipation performance, making it highly ...

State transition and electrocaloric effect of BaZr$_{x}$Ti$_{1-x}$O$_3$: simulation and experiment

, 2016
The electrocaloric effect (ECE) of BaZr$_{x}$Ti$_{1-x}$O$_3$ (BZT) is closely related to the relaxor state transition of the materials. This work presents a systematic study on the ECE and the state transition of the BZT, using a combined canonical and ...

Synergistic Processes for Microstructure Engineering and Enhanced Dielectric Functionality in PVDF‐Based Systems

Macromolecular Rapid Communications, Volume 47, Issue 1, 9 January 2026.
This work shows that tuning solvent polarity and evaporation rate during casting significantly improves the microstructure and dielectric properties of PVDF‐based co‐ and ter‐polymers films. Using highly polar, fast‐evaporating solvents enhances crystallinity, electroactive phase formation, and dielectric performance, offering a simple, energy ...

Giant electrocaloric effect around T$_c$

, 2012
We use molecular dynamics with a first-principles-based shell model potential to study the electrocaloric effect (ECE) in lithium niobate, LiNbO$_3$, and find a giant electrocaloric effect along a line passing through the ferroelectric transition.
