Additively Manufactured Nanotechnology and Origami-Enabled Flexible Microwave Electronics Inkjet printing and additive manufacturing technologies (AMT) are introduced for the fabrication of flexible RF/microwave electronics and sensors.

Inkjet printing on flexible paper and additive manufacturing technologies (AMT) are introduced for the sus- tainable ultra-low-cost fabrication of flexible radio frequency (RF)/microwave electronics and sensors. This paper covers ex- amples of state-of-the-art integrated wireless sensor modules on paper or flexible polymers and shows numerous inkjet- printed passives, sensors, origami, and microfluidics topolo- gies. It also demonstrates additively manufactured antennas that could potentially set the foundation for the truly conver- gent wireless sensor ad-hoc networks of the future with en- hanced cognitive intelligence and ''zero-power'' operability through ambient energy harvesting and wireless power transfer. The paper also discusses the major challenges for the realization of inkjet-printed/3-D printed high-complexity flexible modules as well as future directions in the area of environmentally-friendly ''Green'') RF electronics and ''Smart- House'' conformal sensors.
