New 'Spray-On' Memory Could Turn Everyday Items Into Digital Storage Devices (duke.edu)
Researchers at Duke University have developed "spray-on" digital memory using only an aerosol jet printer and nanoparticle inks. An anonymous reader quotes Duke Today:
The device, which is analogous to a 4-bit flash drive, is the first fully-printed digital memory that would be suitable for practical use in simple electronics such as environmental sensors or RFID tags. And because it is jet-printed at relatively low temperatures, it could be used to build programmable electronic devices on bendable materials like paper, plastic or fabric...
The new material, made of silica-coated copper nanowires encased in a polymer matrix, encodes information not in states of charge but instead in states of resistance. By applying a small voltage, it can be switched between a state of high resistance, which stops electric current, and a state of low resistance, which allows current to flow. And, unlike silicon, the nanowires and the polymer can be dissolved in methanol, creating a liquid that can be sprayed through the nozzle of a printer.
Amazingly, its write speed is three microseconds, "rivaling the speed of flash drives." The information can be re-written many times, and the stored data can last for up to 10 years.

My fountain pen turns everyday objects into digital storage devices. (When it doesn't, I use a felt tip pen instead.)

Now any household object, and even the building itself can be a data storage device......
I hate to move. My old house is full of so many old memories ...and I have nothing to back them up to.
