A Wireless Chip the Size of Grain!

HP has announced the development of a miniature, wireless data chip that according to the company, is capable of providing broad access to digital content in the physical world.

"Memory Spot", a research team at HP Labs, has developed this memory device based on CMOS (a widely used, low-power integrated circuit design). The chip is just about the size of a grain of rice or smaller (2 mm to 4 mm square). These chips can be fixed on a sheet of paper or stuck to any surface, and the company says, will eventually be made available as a booklet with self-adhesive dots.

Some of the potential applications of this device include storage of medical records on a hospital patient's wristband; provision of audio-visual supplements for postcards and photos; help in the pharmaceutical industry's fight against counterfeit; beefing-up of identity card and passport security; and supply of additional information for printed documents.

Ed McDonnell, memory spot project manager, HP Labs, said, "The Memory Spot chip frees digital content from the electronic world of the PC and the Internet, and arranges it all around us in our physical world."

HP claims that the chip has a ten megabits-per-second data transfer rate, which is ten times faster than Bluetooth wireless technology, and comparable to Wi-Fi speeds, giving users instant retrieval of information in audio, video, photo, or document form.
