Researchers 3D-print WiFi-connected objects that don't need power

Engadget ----------- Researchers at the University of Washington have developed a way for 3D-printed plastic objects to transmit information via WiFi without the help of batteries or electronics. And they show that it can be done with commercially available plastics and WiFi receivers. "Our goal was to create something that just comes out of your 3D printer at home and can send useful information to other devices," Vikram Iyer, a graduate student on the project, said in a statement. "But the big challenge is how do you communicate wirelessly with WiFi using only plastic? That's something that no one has been able to do before."
