Soft Ionic and Electronic Triboelectric Nanogenerators: Toward Attachable and Implantable Biomedical Applications

open access: yesAdvanced Materials, EarlyView.
This review provides an overview of triboelectric nanogenerator (TENG)–based biomedical applications by classifying studies into electronic and ionic systems across attachable and implantable platforms. It summarizes key material choices, device structures, and working mechanisms that characterize current TENG‐based research, and outlines six future ...

Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain

open access: yesAdvanced Materials, EarlyView.
A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,

Ultrafast Vertical Organic Electrochemical Transistors With Ion‐Permeable Conductive Polymer Top Electrodes

open access: yesAdvanced Materials, EarlyView.
Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a

Photo‐Patternable PEDOT:PSS for High Performance Organic Electrochemical Transistors

open access: yesAdvanced Materials, EarlyView.
Organic mixed ionic‐electronic conductors, such as PEDOT:PSS, are a special class of material capable of dual conductivity, making them a perfect choice to bridge biology and man‐made technology. PEDOT:PSS can be photo‐patterned by blending it with a photo‐sensitive interpenetrating network.

Stoichiometry‐Programmed MXenes via Precursor Engineering for High‐Performance EMI Shielding and Energy Storage

open access: yesAdvanced Materials, EarlyView.
Precursor carbon stoichiometry programs internal strain and oxygen substitution in Ti3AlCxO2‐x, deterministically switching Ti3CxO2‐xTz MXenes between highly aligned 2D nanosheets and spontaneous 1D nanoscrolls. This synthesis‐stage architecture control enables ultrathin X/W‐band EMI shielding with outstanding mass‐normalized performance and bending ...
