During usage, printed electronic components are often stretched, bent, folded, and/or twisted to conform underlying structure. In this article, tests have been developed for characterizing the mechanical and high-frequency electrical behavior of inkjet-printed patch antennas on flexible polyethylene terephthalate (PET) substrates under uniaxial biaxial bending. A antenna is designed a single resonant frequency 5 GHz in free space. Polycarbonate cylindrical mandrels 1.25" diameter special...
Due to the increased popularity of wearable devices, designing flexible hybrid electronics (FHE) is becoming increasingly critical. Some emerging systems that require FHE include wearables, energy-harvesting sensory networks, and electrocardiogram monitors. These designers account for different actions, such as stretching, bending, twisting, etc. Accounting actions requires models components capture behavior under these actions. This work focuses on characterizing effects bending two...
This paper discusses the electrical and mechanical characterization of an inkjet-printed patch antenna under uniaxial biaxial bending. A 30 mm × 40 design with a truncated copper ground plane was designed fabricated by inkjet printing on polyethylene terephthalate (PET) substrate. The samples were then fixtured cylindrical polycarbonate mandrels as well 3D printed saddle-like structures using polylactic acid (PLA).

Glass has been shown to be a capable core substrate material for high frequency applications. In this paper we examine the capabilities of ultra-thin glass as flexible that can used The two stack-ups discussed in are 60 μm total thickness with (Schott AF32) 30 thickness. One stack-up uses 15 JSR GT-N01 buildup dielectric and other Taiyo Photo Imageable Dielectric. Since neither these have previously electrically characterized, characterizes both up 110 GHz using microstrip ring resonators...
Flexible hybrid electronics (FHE) is a promising technology enabling many applications in biomedical, communication, energy harvesting and internet of things (IoT) areas. To realize FHE applications, the components devices used mentioned technologies need to be electrically characterized under various flexible conditions such as stretching, bending, twisting, folding.
