Ferroionic Electrostatic Landscapes Enabling Wireless Energy Harvesting, Storage, and Sensing

Advanced Electronic Materials, EarlyView.
By integrating experiments and electrostatic field simulations, we show that long‐range wireless coupling in Li‐based ferroionics devices emerges from the cooperative interaction between ionic migration and electronic polarization. This coupling sustains self‐polarized electrostatic fields across centimeter‐scale air gaps without external bias or ...

Cost‐Effective Ti/Al/Ni Multilayer Neural Probes With In Vivo Recording Performance Comparable to Ti/Au Neural Probes

Advanced Electronic Materials, EarlyView.
In this study, we developed a cost‐efficient neural probe by replacing traditional gold with an aluminum‐based Ti/Al/Ni multilayer stack. Optimizing this metal architecture suppressed oxidation and ensured robust electrical stability, achieving signal quality comparable to standard gold probes. It enables a highly accessible and economical solution for

Discovery of Novel Materials with Giant Dielectric Constants via First‐Principles Phonon Calculations and Machine Learning

Advanced Intelligent Discovery, EarlyView.
We discovered novel materials with giant dielectric constants by combining first‐principles phonon calculations and machine learning. Screening 525 perovskites identified six candidates. RbNbO3 was synthesized under pressure and showed ε ≈ 800–1000. This validates our framework as a powerful tool for high‐performance dielectric materials discovery.

Recessed Microelectrodes as a Platform to Investigate the Intrinsic Redox Process of Prussian Blue Analogs for Energy Storage Application

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
A microelectrochemical analytical tool is proposed for the accelerated evaluation of the intrinsic electrochemical performance of Prussian‐blue analogues as solid active materials in Na+‐based batteries. By confining the solid active material inside a recessed microelectrode, accelerated voltammetric and galvanostatic cycling at high C‐rate become ...
