Flexible and stretchable 3D electronic microstructures that are promising for biomedical applications can be fabricated by a new technique.
Flexible electronics are attracting interest for use as wearable sensors and other biomedical applications. Most of them are made by stamping membranes grown on silicon onto soft polymers, but this method can generally only be used to produce 2D structures.
Now, a team led by researchers from Griffith University in Australia has demonstrated a method that can produce 3D flexible electronic structures from transparent semiconductors with wide bandgaps.
The team demonstrated their technique by using to it produce various structures, including one resembling a spider web and another having a flower-like structure.
The researchers anticipate that their fabrication technique will make it much easier to produce 3D bioelectronic interfaces.
