HP Develops Grain-Size Wireless Chip

MANHASSET, N.Y. — Hewlett-Packard Co. has developed a miniature wireless data chip the company said could broaden access to digital content in the physical world.

Measuring 2 to 4 millimeters2—the size of a grain of rice—and could be attached or embedded in almost any object to make available information and content now found mostly on Web devices.

The chip, developed by the Memory Spot research team at HP Labs, is a CMOS memory device with a built-in antenna. According to the company, the chip could be embedded in a sheet of paper or attached to surfaces. It could eventually be available in a booklet as self-adhesive dots.

Potential applications include storing medical records on a hospital patient's wristband, providing audio-visual supplements to postcards and photos, preventing counterfeiting in the pharmaceutical industry, adding security to identity cards and passports and supplying additional information for printed documents.

"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," Ed McDonnell, Memory Spot project manager, HP Labs, said in a statement.
