#Injectable Implants Could Help Crack the Brain Codes A new type of flexible electronic device shows promise for long-term brain mapping
Recording them requires inserting electrodes into the tissue. But the rigid devices traditionally used to record these signals,
Now researchers have shown that a new type of flexible electronic device which can be delivered via injection,
One current therapeutic use of implanted electronics is called deep brain stimulation, which is approved FDA and used to treat Parkinson disease.
The therapy involves inserting electrodes into certain regions of the brain and producing electrical pulses meant to regulate abnormal ones.
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,
and this echanical mismatchleads to tissue damage and immune response, he says. Over time the devices tend to lose their ability to record
In recent years, a lot of progress has been made in research labs toward designing new kinds of implantable electronic devices made of more flexible
and biocompatible materials (see ireless Micro LEDS Control Mouse Behavior, but none have overcome this problem,
and, according to the researchers, the mesh is several orders of magnitude more flexible than any previous implantable electronic device.
and also house electronic sensors for taking measurements from those cells. That demonstration suggested that the technology was potentially useful for measuring cellular activity.
Tiny electronic devices, such as sensors and electrode stimulators, can be built into it. A scaffold that is a centimeter and a half in width can fold into a size small enough to be injectable through a needle
which predicts that the number of transistors on a chip doubles every two years, has held steady since 1975.
One way the consumer electronics industry is trying to fix this is by aligning with wireless charging technologies like Qi and Rezence.

This week at the International Consumer electronics Show in Las vegas, Nvidia, a leading marking of computer graphics chips, unveiled a vehicle computer called the Drive PX that could help cars interpret
Nvidia already supplies chips to many car makers but engineers at those companies usually have to write software to collect
and process data from various different sensor systems. Drive PX is more powerful than existing hardware,
and process sensor data. The computer uses Nvidia new graphics microprocessor, the Tegra X1. It is capable of processing information from up to 12 cameras simultaneously,
and it comes with software designed to assist with safety or autonomous driving systems. Most impressive, it includes a system trained to recognize different objects using a powerful technique known as deep learning (see 0 Breakthrough Technologies 2013:

such as a gas sensor, an optical switch, and even to reinforce composite materials to make them stronger.
The big advantage of black phosphorus over graphene is that it has a natural bandgap that physicists can exploit to make electronic devices
such as transistors. But Hanlon and co say the newfound availability of black phosphorus nanosheets has allowed them to test a number of other ideas as well.
That immediately makes black phosphorous a decent ammonia detector. Hanlon and co say the material could detect ammonia at levels of around 80 parts per billion.
#AMD's new High Bandwidth Memory will power the graphics cards of the future Sitting down to talk graphics memory isn't usually anyone's idea of a good time
but these are the chips that underpin everything from GTA V to 4k Netflix -and AMD just unveiled the memory technology it wants to power the GPUS of the future.
Seven years in the making, High Bandwidth Memory (HBM) promises to provide huge improvements over the GDDR5 memory currently sitting inside AMD's top-end graphics cards
It changes the layout of memory chips from the ground up-chips are stacked vertically like skyscraper floors in a 3d pattern (not unlike 3d technology used in SSD),
and new interconnector technology ensures low power consumption and high bandwidth capabilities. Temperatures come down too. Graphics cards will soon be shrinking significantly thanks to HBM.
Key to the potential of HBM-as its name suggests-is the bandwidth, or the amount of data it can cope with at once.
"There's also a massive increase in bandwidth. We have blown basically through the bandwidth-per-watt wall...
I'm astounded at what we've been able to achieve.""With Nvidia working on next-generation graphics technology of its own,
your next phone could be made of wood Engineers hunting for a way to make electronics more sustainable have hit on a novel invention-a semiconductor chip made almost entirely out of wood.
The idea is that instead of making chips from petroleum-based plastic, we'd be able to use cellulose nanofibril-a flexible,
"The majority of material in a chip is support. We only use less than a couple of micrometers for everything else,
"The result is based a bio chip, which is not only flexible enough to use in consumer electronics but an order of magnitude more environmentally-friendly."
"The chips are so safe you can put them in the forest and fungus will degrade it.
They become as safe as fertilizer, "said Ma. He added:""Mass-producing current semiconductor chips is so cheap,
and it may take time for the industry to adapt to our design. But flexible electronics are the future,
and we think we're going to be well ahead of the curve

#Semiconductor crystals could be key to extending Moore Law IBM researchers have developed a process for growing crystals made from semiconductor materials,
will allow integrated circuits to continue reducing in size and cost, while simultaneously increasing performance. This will enable an extension of Moore Law,

it is likely to be the smallest possible size for a transistor and the hard limit for Moore law.
The transistor is made of a single molecule of phthalocyanine surrounded by ring of 12 positively charged indium atoms placed on an indium arsenide crystal,
For comparison a strand of human hair, at 100, 000nm thick, is about 600,000 times wider than the atoms surrounding the new transistor.
The transistor represents a big step forward toward quantum computing, and was made possible using a scanning tunnelling electron microscope to place atoms in exact positions
and control the electron flow through the gate. Typically scientists working to this atomic scale have struggled to reliably control the flow of electrons
and can jump outside of the transistor, rendering it useless. The international team of researchers from Paul-Drude-Institut für Festkörperelektronik and the Freie Universität Berlin, Germany, the NTT Basic Research Laboratories, Japan,
and the US Naval Research Laboratory also discovered unexpected behaviour from the transistor. The orientation of the molecule of phthalocyanine an organic molecule typically used in dyes at the heart of the transistor is affected by charge.
Its orientation could be changed by altering its charge, leading to more than a simple on-off switch-like state as seen in traditional transistors.
The work proves that precise control of atoms to create a transistor smaller than any other quantum system available is possible
and opens the door to further research into harnessing these tiny transistors for computers and systems with orders of magnitude more processing power than today machines.
Chip manufacturers have struggled to maintain Moore law, which dictates that processing power will double every 18 to 24 months,
primarily through the doubling of the number of transistors they can fit on a chip.
The more transistors that can fit on a chip, the more powerful it can be.
