'hough not the first attempts at implanting electronics into the brain deep brain stimulation has been used to treat a variety of disorders for decades the nano-fabricated scaffolds operate on a completely different scale. xisting techniques are crude relative
But with our injectable electronics, it as if it not there at all. They are one million times more flexible than any state-of-the-art flexible electronics
and have subcellular feature sizes. Theye what I call euro-philicthey actually like to interact with neurons..
After injection, the input/output of the mesh can be connected to standard measurement electronics so that the integrated devices can be addressed

Sourcing neodymium and dysprosium from used electronics rather than the ground would increase their supply at a fraction of the financial, human and environment cost.
The team believes that the sensors can be used not just to create more flexible electronics

#Influential Interfaces Lead to Advances in Organic Spintronics Spintronics is an emerging field of electronics in
a spintronic circuit needs a well-controlled source of spin-polarized electrons that are injected into a transport channel material,
Spintronic devices made of inorganic materials are used today for read heads on hard disk drives magnetoresistive random access memory (MRAM),
and ferromagnets are important to the development of organic spintronics because the interface plays a critical role in determining the efficiency of spin injection and detection.
This finding suggests that the rapid oxidation of cobalt does not necessarily have to be a limiting factor in organic spintronics.

Until now scientists and engineers have relied on shrinking electronics to make them faster, but now increasingly clever methods must be used to sustain the continued progression of electronics technology,
as we reach the limit of how small we can create a transistor. One such method is to separate the flow of electron spin from the flow of electron current
In a spintronic device you don have to use a ferromagnet. You can use either a paramagnetic metal or a paramagnetic insulator to do it now

One current therapeutic use of implanted electronics is called deep brain stimulation, which is approved FDA and used to treat Parkinson disease.
Today technology is limited, not by the electronics, which are already eally powerful, but because the interface between the brain tissue and the electronics is far from ideal,
says Charles Lieber, a professor of chemistry and chemical biology at Harvard university. Existing implantable electrodes are too large and rigid,
Electronics giant Toshiba and chip makers Marvell and Nvidia are among those already showing interest;
