Using additive manufacturing techniques like inkjet and 3D printing, a group of researchers in Georgia have built very complex structures at low cost by printing conductive inks or dielectric materials deposited on a substrate to make “planar circuits,” antennas, or sensors of arbitrary heights and thicknesses. John Kimionis and Professor Manos Tentzeris developed their origami-style folding technique where 2D structures can be shaped into a variety of 3D configurations from thin, easily foldable substrate materials like paper. They add that they can also fabricate the devices with a 3D printed structure made of flexible polymer or harder materials which feature hinging design functions.
