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 :
