By selectively engineering the surface roughness of micro-light-emitting-diode chips, and thus the strength of the van der Waals forces that bond them to a substrate, large-area displays can be created via a fluidic-assisted transfer method.
Multilayer hexagonal boron nitride can be synthesized over large areas and used to enhance mobility in graphene heterostructures, illustrating the potential of the material as an insulator in commercial two-dimensional electronics.
An embedded 3D printing technique — which uses an alginate–polyacrylamide hydrogel supporting matrix and a conductive silver–hydrogel ink — can be used to fabricate hydrogel electronic devices containing various different embedded circuits.
By controlling ion-dynamic capacitance, electrolyte-gated transistors can be switched between different operating modes, providing flexible neural network implementations.
