Ultra‐Flexible µ‐ECoG Arrays Based on PEDOT:PSS Micropillars

open access: yesAdvanced Materials Interfaces, EarlyView.
This work demonstrates an efficient procedure for fabricating ultra‐flexible neural interfaces endowed with micropatterned microelectrodes to increase surface area and characterized by extremely low impedance values to enable high‐quality recordings. The home‐built device has been shown to record somatosensory evoked potentials in vivo with exceptional

Durable Self‐Powered Wireless IoT Machine Condition Monitoring System Based on an Auto‐Switching Non‐Contact Centrifugal TENG

open access: yesAdvanced Materials Technologies, EarlyView.
A durable self‐powered Intelligent wireless machine condition monitoring system is developed from an auto‐switching non‐contact centrifugal Triboelectric Nanogenerator (TENG) energy harvester, TENG vibration sensor, and Thingspeak cloud platform. The designed TENG‐based harvester generates a high‐power output of 25 and power density (284W m−3) and ...

Time‐ and Frequency‐Domain THz Imaging for the Characterization of Subwavelength Tags in Anticounterfeiting Devices

open access: yesAdvanced Materials Technologies, EarlyView.
Anticounterfeiting optical devices typically rely on random surface patterns revealed under IR/vis/UV light. Despite its security, this method suffers from the unavoidable deterioration of exposed superficial patterns. The proposed technique utilizes the high penetration depth and resolution of THz radiation to reveal submillimeter metallic patterns ...

Going from Inner‐Skinned to Outer‐Skinned Polyelectrolyte Multilayer Based Hollow Fiber Nanofiltration Membranes

open access: yesAdvanced Materials Technologies, EarlyView.
New negatively charged hollow fiber support membranes with an inverted porous structure are fabricated. These supports are coated with polyelectrolytes to form an outer‐skinned polyelectrolyte multilayer membrane. The membranes show a 3.8x increase in active membrane surface area compared to conventional inner‐skinned polyelectrolyte multilayer ...
