“This proof-of-concept device mimics the human eye’s ability
to capture light and the brain’s ability to process that
visual information, enabling it to sense a change in the
environment instantly and make memories without the need
for using huge amounts of data and energy,” Walia said.
“Current digital systems, by contrast, are very power
hungry and unable to keep up as data volume and complexity
increases, which limits their ability to make ‘true’
real-time decisions.”
The research is published in Advanced Materials Technologies.
Walia and Al-Hourani are corresponding authors and Mr.
Thiha Aung, a PhD scholar at RMIT, is first author.
RMIT has filed a provisional patent

Interesting little article. The new device is based
on micro-defect molybdenum disulfide films. The way
it detects light is closer to 'analog' than digital.
There are also sub-layers that give it a sort of
memory, making it much more responsive to CHANGES
in the image without heavy digital calx and the
related power consumption. Basically, it mimics
retinal receptors and a layer or two of retinal
neural cells that enhance the image and are made
to notice changes.
You don't really 'program' these things, they are
designed to already act like retinas.
Various industrial (maybe mil) and self-driving
vehicle uses are the first likely applications.
MoS2 has become a rising star in the 'semiconductor'
universe. New tricks are revealing a large array of
capabilities. New techniques for much finer control
of crystal lattice defects and impurity insertion
make a lot of new things possible. "Strain" on the
lattice also yield interesting effects. Other
'exotics' like silicon carbide and graphene are
also coming up quickly.
If there's a future Venus rover - there will likely
be no silicon electronics, just these newer stars.
They can stand much more heat and yet handle high
power flows. And yes, they HAVE made MoS2 cpus :

A RISC-V cpu IS good enough for a Venus rover.
