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......
This has security ramifications, And also ramifications for law enforcement.
Occassional/Typical seizure warrant language for an investigation these days is "Any data storage device", basically data storage is a treasure trove, so anyone under investigation or potential suspicion of having information or participation in any kind of crime or illegal act will have all their data storage devices seized, in order to do forensic analysis and search all data for possible leads or connections on any pending cases, or in order to open new cases.
But if people can print data storage on ANYTHING, then EVERYTHING including clothing will have to be thoroughly examined to see if it might contain some printed-on memory.

I hate to move. My old house is full of so many old memories ...and I have nothing to back them up to.
