*Tiny wireless Implantable memory chip debuts*
HP has developed a tiny memory chip that can swap data wirelessly
The chip contains memory, modem, antenna and microprocessor
A chip the size of a grain of rice that can store 100 pages of text and
swaps data via wireless has been developed by Hewlett-Packard.
The tiny chip was small enough to be embedded in people, animals and
almost any object, said HP.
The chip could be used to ensure drugs have not been counterfeited,
implanted in patients in hospitals or to add sounds or video to
postcards, said HP.
But it warned that the device was at least two years away from being a
finished product.
Quick chip
The chip, developed by the Memory Spot research team at HP, is 2-4mm
square and current versions can hold up to 512 kilobytes of data.
HP said the amount of memory onboard the tiny chip was likely to grow in
future versions.
Data can be moved in and out of the chip at speeds of up to 10 megabits
per second - far faster than is possible with other short-range radio
systems such as Bluetooth or Radio Frequency ID tags.
"This really bridges the digital and physical worlds," said Howard Taub,
associate director at HP Labs. "The digital data is attached to the
physical object it's related to."
Mr Taub speculated that the tiny chip could be used to identify drugs
and spot fake pharmaceuticals or in hospitals to log all the treatment a
patient has received.
Because the chips were so small and easy to make they could be embedded
in documents as they were printed, stuck to any surface or made into a
book of self-adhesive dots.
"There's no question that it has long-term potential," said Tim Bajarin,
head of Californian market researcher Creative Strategies.
All the components to make the chip, including modem, antenna,
microprocessor and memory, can be fabricated as a single unit helping to
keep unit costs low. HP speculated that once in production the devices
could cost as little as one dollar each.
No battery is needed because devices reading data from the chip will
provide power by induction.
HP said it would show the chip to standards bodies in the hi-tech
industry with a view to getting it widely adopted. It warned that the
chip was at least two years away from commercialisation.
The Memory Spot chip has been developed over the past four years by
researchers at HP's research laboratory in Bristol, UK.
