Ambient‐Spray Ni–Cu(–O)/Ag Nanowire Transparent Heaters for High‐Temperature Heating and Far‐/Near‐Field EMI Suppression

Advanced Materials Interfaces, EarlyView.
A vacuum‐free, ambient‐spray Ni–Cu(–O)/Ag nanowire transparent‐heater platform is realized via conformal junction‐shell engineering and silica–hybrid overcoating, enabling robust high‐temperature heating together with GHz‐band far‐field EMI shielding and near‐field magnetic‐noise attenuation.

Bandgap‐Dependent Band‐to‐Band Tunneling in Carbon Nanotube Transistors

Advanced Materials Interfaces, EarlyView.
We systematically investigate bandgap‐dependent BTBT in SWCNT transistors by comparing wide‐bandgap (6,5) (Eg≈1.13 eV), medium‐bandgap HiPco, and narrow‐bandgap Arc‐discharge (Eg≈0.59 eV) SWCNT networks. The narrow‐bandgap networks show stronger BTBT, higher off‐state leakage, and lower on/off ratio, while wide‐bandgap (6,5) devices suppress BTBT and ...

Optimization study on misalignment tolerance of a wireless power transfer system with double-layer vertical DD coils

Wireless Power Transfer
To address the issue of coil misalignment in magnetically coupled wireless power transfer (WPT) systems, which causes fluctuations in mutual inductance, a reduction in the magnetic coupling coefficient, and a decline in transmission efficiency, this ...

Maskless Fabrication of PLA‐Based Neural Arrays for CNS Recording and Stimulation

Advanced Materials Interfaces, EarlyView.
Biodegradable neural interfaces enable bidirectional communication with the CNS. Through electrochemical characterization, ageing tests with impedance monitoring, and in vivo validation, we assess the performance of PLA‐based epicortical and spinal implants.

Construction and analysis of precise circuit model for SWPT considering parasitic capacitance

Wireless Power Transfer
Due to seawater's high conductivity and dielectric constant, the traditional pure inductance model used in air cannot accurately describe the coil model in seawater wireless power transfer (SWPT).

Hierarchical Multi‐Material Architectures With Gradient Design for Dynamic‐Range Flexible Tactile Sensing

Advanced Materials Technologies, EarlyView.
Hierarchical multi‐material TPMS lattices are engineered as flexible tactile sensors by combining soft and stiff elastomeric layers with a conformal conductive coating. The bilayer architecture delivers sensitivity at low pressures while maintaining a broad detectable range under large loads, enabling reliable pressure and vibration monitoring for ...

Design of low-loss PCB Litz wire with planar spiral coil for wireless power transfer

Wireless Power Transfer
Planar spiral coils in high-frequency wireless power transfer systems suffer from increased loss due to skin and proximity effects. The PCB Litz wire structure is proposed to suppress eddy current losses and improve the quality factor.

Solid Particle‐Liquid Metal Mixtures for Robust High‐Current Interconnects in Stretchable Electronics and Soft Robotics

Advanced Materials Technologies, EarlyView.
Metallic microparticles dispersed in liquid metal interconnects mitigate electromigration‐induced failure by reconfiguring internal current density distributions. These fillers facilitate the growth of a robust, protective gallium oxide shell at elevated temperatures, shifting the failure threshold toward a thermal limit.

Research on constant voltage and constant current dual-load wireless power transfer system based on composite control method

Wireless Power Transfer
Existing wireless power transfer (WPT) systems often fail to simultaneously achieve constant-voltage (CV) and constant-current (CC) outputs when charging multiple devices. To address this limitation, this paper proposes a dual-load WPT system with CV and
