Researchers at the University of Washington (UW) have developed a technique for three-dimensionally (3D) printing plastic objects that communicate with Wi-Fi devices without batteries or electronics.
The method applies Wi-Fi backscatter technology to 3D geometry to create wireless devices that are easy to print using commodity 3D printers.
The researchers built non-electronic analogues for each electronic component using plastic filaments, then integrated them into a single computational design.
Explained UW’s Shyam Gollakota, “We are using mechanism actuation to transmit information wirelessly from these plastic objects.”
The team has released its computer-aided design (CAD) models to 3D-printing hobbyists so that they can create their own Internet of Things objects.
