Fully Inkjet‐Printed Organic Electrochemical Transistors: A Path Toward All‐Organic Electronics

Advanced Materials Technologies, EarlyView.
Fully printed organic electrochemical transistors eliminate the metal electrodes used in conventional printed organic electronics. This work demonstrates the state of the art in three applications using PBFDO and PEDOT:PSS materials: a single‐material strain sensor for real‐time detection of finger flexion, an ion sensor for monitoring aqueous NaCl ...

Cellulose‐Nanofiber‐Based Layered Sub‐Terahertz Absorbing Sheets for B5G/6G Applications

Advanced Materials Technologies, EarlyView.
We report a sub‐terahertz absorber made of biodegradable cellulose‐nanofiber (CNF), potentially useful for B5G/6G devices to achieve electromagnetic compatibility in an eco‐friendly way. The absorber is 120 µm thick and consists of two carbon‐nanotube‐dispersed CNF layers and one pure CNF layer.

Laser Micromachining of Liquid Metal Patterns for Stretchable Electronic Circuits

Advanced Materials Technologies, EarlyView.
A cleanroom‐free fabrication strategy combines UV‐laser micromachining with a copper foil wetting layer to rapidly produce high resolution, liquid metal based stretchable electronic circuits on diverse substrates. The scalable, maskless process enables complex circuit designs (<$<$3 h, ∼$\sim$15/device) with excellent electrical stability under strain,
