Here's an interesting bit of new enabling technology, the Memory Spot.
The experimental chip, developed by the Memory Spot research team
at HP Labs, is a memory device based on CMOS (a widely used, low-power
integrated circuit design) and about the size of a grain of rice or
smaller (2 mm to 4 mm square), with a built-in antenna. The chips could
be embedded in a sheet of paper or stuck to any surface, and could
eventually be available in a booklet as self-adhesive dots.
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, said Ed McDonnell, Memory Spot project manager, HP
The chip has a 10 megabits-per-second data transfer rate 10 times
faster than Bluetooth wireless technology and comparable to Wi-Fi
speeds effectively giving users instant retrieval of information in
audio, video, photo or document form. With a storage capacity ranging
from 256 kilobits to 4 megabits in working prototypes, it could store a
very short video clip, several images or dozens of pages of text.
Future versions could have larger capacities.
Information can be accessed by a read-write device that could be
incorporated into a cell phone, PDA, camera, printer or other
implement. To access information, the read-write device is positioned
closely over the chip, which is then powered so that the stored data is
transferred instantly to the display of the phone, camera or PDA or
printed out by the printer. Users could also add information to the
chip using the various devices.
This could have applications in both wireless medical devices and wireless sensors. I would think the greatest opportunity will be in the telehealth or remote monitoring market.
