Organic Ferroelectric Synaptic Transistors for Neural Image Recognition Networks

Advanced Materials Interfaces, EarlyView.
All organic transistors, where both the dielectric and semiconducting layers are polymeric, are developed as electrical synaptic devices. Two copolymers of PVDF as the dielectric layer with large differences in their saturation polarizability and memory window are chosen.

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

Advanced 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

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

Advanced 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 ...
