It's the future and it makes sense. It could actually save the semicon industry as they are now at a point that they need to produce millions of units of the same chip to recover the design and factory costs. That ain't cheap.
The future is likely that we can print our own chips (the technology exists). Not everybody needs the latest/greatest 22 nm chip to design a useful product.
"they're talking about" For the moment, it will come soon enough if the US patent office dont skrew it up for the prior art Open Hardware designers etc...
for instance a version of this http://www.stfc.ac.uk/News+and+Events/5194.aspx
"Miniaturising electronics to the nanoscale"
could be integrated used in future 3D printing in time
along side this http://source.theengineer.co.uk/materials-and-chemicals/plastic-microstructures-with-nanoscale-features-are-fabricated-at-greater-speed/2009271.article for the [flexible] packaging to start with
as more Nano scale micro fluidic's Additive manufacturing/3D printing come online from the smaller industrial units looking for new markets...it#s not just good for biological 100nm manipulation etc http://www.frogheart.ca/?tag=nanocellulose
as you can also do that scale today
such as the kick starter funded FORM 1: An affordable, professional 3D printer
3D Printing Will Be More Fun Than even LEGO :)
you just need to pull yourself out the doldrums and look to the "UK Plastic Electronics Show" and their EU partners for inspiration and collaboration being pulled directly out of their Uni's lab's etc
If you can deposit conductors, then you can deposit insulators and semiconductor material.
Take a look inside most IC dies and you will see layers of each type of material.
Using a 3D printer approach is within the possibility for future circuts. For experimentation, size will mean little verses getting a prototype circuit working inside 24 hours.
Just a thought.
For me? I'd use it to make cases for Gabotronics' oscilloscope modules. I bought one of each for Black Friday and intend to make both of them into hand-held, battery-operated test equipment. For my plans, they have just the right form factor and specs. Being able to print a case with a firm grip on the module legs and space for a good Li-Pol battery and charger board (and maybe some day the charger will be printed as well!) fits the bill very nicely. Only one more thing needed: The ability to make thermally-conductive but electrically-isolated heat sync buttes in to the case to carry off heat from the ICs. I'm not all that good with metal working, but I can get a laser etcher or 3d printer to work for me!
Ah! A mug which can tell how full it is. Just what the world has been waiting for. Now all I need is a bed that tells me if I am asleep so I dont need to toss and turn, and a device which tells me if its daytime or night time so I dont need to open my eyes when the bed tells me I am awake. *Sigh* Luxury!
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
