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.

I would use it on my hair.
What the fuck is wrong with consumerism. It doesn't even know what convenience is anymore.
SPY ON MEMORY
ya know i want to know what where and when you are somewhere
lil tiny spray you never know.....
The ugliest ever stripper I encountered was this woman easily in her early 70s. White pubes, I kid you not. She had breasts like two dangling sacks of potatoes. Her hair was just that, like sprayed on glitter. She had so much hair spray she turned her hair into this Marge Simpson kind of penis and testacles. Totally out of proportion and only a foot high, but kinda looked like Marge Simpson but only shorter. That is one thing that I can never get out of my memory. Thanks for sharing.
Well, I guess this spells the end of the 'paperless office' revolution.
Going to have to recover all those old loose-leaf binders to repurpose tham as data storage files -lol-
Who'd a thought the old paper junk could actually be digitized, in the most literal sense.
redneck geek
What happens if you spray it on your balls and then it needs to be used as evidence later on?
My fountain pen turns everyday objects into digital storage devices. (When it doesn't, I use a felt tip pen instead.)

Until you spill a drink on it.
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.
In order to use the memory, you're going to need to include a bunch of other electronics, like an RFID tag. And if you already have the electronics, you may as well put conventional memory in there.
I doubt any sprayed on material will last ten years from routine washing and drying cycles.
Don't tell Trump! We can't let him know that Obama sprayed all his very long, made in China ties with this stuff to record everything he says!
Spray On memory.
Spray On solar cells.
What we need now is Spray On common sense, and the world will be a better place.
that was your mom
If you search you'll find a similar product that would allow you to paint your walls and turn them into display monitors.
Another Millennial Masterpiece brought to you by the worthless generation of idiots.

Q.E.D.
Because they keep forgetting things.
Be thankful you have never had a post-op tranny hike its skirt up to prove to a lounge of uninterested people that it was "a real woman". I nearly threw up.
its like a train wreck, you have to look
Is that a flash drive or are you just happy to see me?
Yes and yes.
Spraying this on your penis gives new meaning to expandable storage.
Do we have an idea of how much density (byte per surface unit) it can achieve?

Not if you have erectile dysfunction, you insensitive clod!

I hate to move. My old house is full of so many old memories ...and I have nothing to back them up to.
How do you address individual cells? It needs to be "sprayed on a substrate+ that does such. Otherwise as has been pointed out a pen does pretty much as well, with any webcam taking care of the traduction and addressing.
As for "able to be printed ..." most nozzle printers (FDM) have nozzles of about 0.4mm ... say you could use a 0.1mm that gives a max areal density (much less in practice) of 100 bits/mm or about 70k bits per in^2 ... maybe a millionth of a modern hard disk.
Why is this exciting again?
