3D Printing Wireless, Connected Household Objects

University of Washington  researchers have developed a way to 3D print plastic objects and sensors capable of communicating wirelessly with other smart devices, without the need for batteries or other electronics. They have 3D printed eyeglass frames, armbands, and artistic models with embedded magnetic data. They also propose 3D printed application prototypes including buttons, smart sliders, and physical knobs that wirelessly control music volume and lights as well as smart bottles that can sense liquid flow and send data to nearby RF devices.
