High Electrical Conductivity Induced by Surface Confinement Effect in Heterostructured Multifunctional Nanofiber Composite Films for Low‐Reflection Electromagnetic Interference Shielding

open access: yesAdvanced Science, EarlyView.
Spray‐coated PVA‐co‐PE/AgNW/MXene films achieve 60.2 dB EMI shielding (8–20 GHz) with low reflection (R = 0.13) at 5.4 wt.% loading. The 3D conductive network enhances absorption, while the film offers high strength (18.33 MPa), Joule heating, photothermal conversion, flexibility, and flame resistance.

MXene‐Integrated Printed Piezoresistive Flexible Sensors: A Breakthrough in Real‐Time Monitoring for Medical and Smart Applications

open access: yesAdvanced Science, EarlyView.
A chocolate‐inlaid Ag@waffle‐structured MXene is synthesized in this research via template‐directed growth strategy (WSM‐A8). The pressure sensor prepared with the WSM‐A8 presents the highest ΔI/I0 response intensity among the reported MXene‐based piezoresistive sensors with satisfactory sensitivity, outstanding structural stability, and superior ...

Design of A Flexible Liquid Metal Tactile Sensor Based on Finite Element Analysis for Pressure and Motion Detection

open access: yesAdvanced Electronic Materials, EarlyView.
In this study, a PVA sacrificial template method is proposed to fabricate microfluidic LM pressure sensors, and LM conductive pathway patterns are designed using FEA. Their study revealed that symmetric patterns and thinner microchannels significantly enhanced the pressure sensitivity of the sensor.
