Xerox researchers have invented a kind of ink that can conduct electricity and be used to put electronic circuits on top of plastics, film, and textiles. That means in the coming years we’ll be able to wear or bend our electronics. You could even print out your electronic gadget on plastic sheets, as if you were printing a document. Silicon chips have long been too expensive or heavy to use in devices that are extremely lightweight. The Xerox team solved this fundamental problem with lighter materials, and it plans to sell the new materials to other businesses that could make wearable electronics.
We have a Xerox solid ink printer, we’d love to be able to drop in a block of silver and print up some hardware 🙂
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
“this is a knitted fabric that is being developed to solve the lack of 100% soft textile breadboards. It is a striped fabric with a 2.54 mm pitch (the same one you find on standard breadboards) so you can attach components, even IC’s, with little effort. Non conductive stripes are alternated to conductive stripes, made of metal wire. There are currently two ways for attaching components, one is sewing components legs to the fabric and the other one is soldering them. Both materials are in fact chosen so that they resist the temperature of a soldering iron. This fabric has some streatchability, non so much due to the presence of metal fibers. We know very little about washability, but we have good chances that one of the two systems will pass the washability test. In the next couple of weeks we will put it on our shop plugandwear.com, along with explainations of the two techniques for the attaching components.”
Forget solder. There are high-conductivity epoxies. ( one example: http://store.sra-solder.com/product.php/6027/8 but I’m sure you can find others.) You can also get conductive ink now. Print with conductive ink, attach surface-mount parts with epoxy.
