Are We There Yet ?
------------------------
Some two years back I suggested that our
high denomination ( Rs 500 / Rs 2000 )
currency notes should be embedded with RFID
chips ( micro-sensors ) and create a Technology Platform ( in IT
department ) through which such notes can be tracked , through NFC in smart phones carried in everybody’s
pocket
Idea was to put a permanent end to BLACK MONEY generation / accumulation through CORRUPTION
But the problem was :
How to “
power “ ( - although , very small ) those RFID
chips , to be able to reveal their Unique Serial Numbers to a nearby smart
phone / smart watch ( - which , in turn , communicates with the server of
the IT department ) ?
Could following news appearing in today’s Deccan
Chronicle , solve that problem ?
New printable
thin films could help power Internet of Things
Scientists, including one of Indian origin, have
designed printable, organic thin films
for "neuromorphic" computers inspired by the human brain, which will
help power Internet of Things. Internet of Things (IoT) need components
and chips that can handle huge quantities of data.
In 2020, there will already be 50 billion industrial
internet sensors in place all around us. A single autonomous device - a smart watch, a cleaning robot, or a driverless
car - can produce gigabytes of data each day, whereas an airbus may have over
10,000 sensors in one wing alone.
Current transistors in computer chips must be miniaturised
to the size of only few nanometres, and analysing
and storing unprecedented amounts of data will require huge amounts of energy.
Sayani
Majumdar, from the Aalto University in Finland,
along with her colleagues, designed and fabricated the basic building blocks of
"neuromorphic" computers inspired by the human brain.
"The technology and design of
neuromorphic computing is advancing more rapidly than its rival revolution,
quantum computing," said Majumdar.
"The key is to
achieve the extreme energy-efficiency of a biological brain and mimic
the way neural networks process information through electric impulses,"
she said.
In a study published in the journal Advanced
Functional Materials, researchers showed how they have fabricated a new breed
of 'ferroelectric tunnel junctions', that is, few-nanometre-thick
ferroelectric thin films sandwiched between two electrodes.
They have abilities beyond existing technologies and
bode well for energy-efficient and
stable neuromorphic computing. The junctions work in low voltages of less than
five volts and with a variety of electrode materials – including silicon used
in chips in most of our electronics.
They also can retain
data for more than 10 years without power and be manufactured in normal
conditions.
"Our junctions are made out of organic hydro-carbon materials and they would
reduce the amount of toxic heavy metal waste in electronics," said
Majumdar.
"We can also make thousands of junctions a day in
room temperature without them suffering from the water or oxygen in the
air," she said.
"What we are striving for now, is to integrate millions of our tunnel
junction memristors into a network on a one
square centimetre area,"
she added.
"We can expect to pack so many in such a small
space because we have now achieved a record-high difference in the current
between on and off-states in the junctions and that provides functional
stability," Majumdar said.
"The memristors could then perform complex tasks
like image and pattern recognition and make decisions
autonomously," she said.
I urge Shri
Arun Jaitleyji / Shri Ravi Shankar
Prasadji , to invite Sayani
Majumdar and pose to her the challenge of getting India rid of
BLACK MONEY forever
through her invention
But , before reaching out to Sayani , they may want to look up my following
earlier emails on the subject of embedding RFID
chip in high denomination notes :
