چکیده
Direct-write printing was utilized in fabricating a wearable metasurface for frequency filtering at 6 GHz. Using radio (RF) performance and sheet resistance, Rs as metrics, the printed metasurfaces were subjected to wash cycle longevity testing. The on two woven nylon industrial fabrics (70D (EX) 200D (BW) thread masses) featuring polyurethane (PU) coating one side. Two conductive inks, CM127-48 (Creative Materials) PE876 (Dupont) tested , RF performance, stability, longevity. values EX BW similar (0.083±0.013 0.088±0.031 ohm/sq, respectively), while had higher than (0.080±0.015 0.35±0.06 ohm/s). revealed that S21 magnitudes least −30 dB all four ink–fabric combinations, agreement with simulations. Wash testing of comparable decrease magnitude both fabrics. However, samples exhibited minimal shifts peak frequency. Longevity tests combinations demonstrated −29.5 dB, smallest change CM127-48–EX sample. Materials selection may be tailored various design goals electronics.

Review Article Direct-Write Ion Beam Lithography
Patterning with a focused ion beam (FIB) is an extremely versatile fabrication process that can be used to create microscale and nanoscale designs on the surface of practically any solid sample material. Based on the type of ion-sample interaction utilized, FIBbasedmanufacturing can be both subtractive and additive, even in the same processing step. Indeed, the capability of easily creating thr...
متن کامل3D direct-write waveguides in diffusion photopolymers
Three-dimensional direct-write lithography can be used to pattern waveguides into diffusion photopolymer using low-power CW lasers as an alternative to femtosecond writing in glass. We show that polymer chemistry permits significant control of waveguide shape. © 2005, Optical Society of America OCIS Codes: (130.3120) Integrated optics devices, (160.2900) Holographic recording materials, (130.31...
متن کاملDirect-Write Planar Microultracapacitors by Laser Engineering
We have successfully employed laser direct write and micromachining to fabricate high capacity hydrous ruthenium oxide (RuOxHy or RuO2 • xH2O) microultracapacitors. A laser direct-write process is used to deposit uniform pads of RuO2 • 0.5H2O in sulfuric acid under ambient temperature and atmospheric conditions. Ultraviolet laser micromachining is used to tailor the shape and size of the deposi...

Figure SI-1. Line cross-sections corresponding to the AFM images in Figures 1b and 1c. Ge nanoribbons were written at 12 V and 1 !m s-1 and 14 V and 100 !m s-1 respectively. Figure SI-2. Current voltage characteristics measured during deposition. Voltage is measured on the sample. No deposition occurs for negative sample voltages, nor positive sample voltages below 6 volts.
متن کاملThree-dimensional direct-write lithography into photopolymer.
We demonstrate a three-dimensional direct-write lithography system capable of writing deeply buried, localized index structures into diffusion-mediated photopolymer. The system is similar to that used for femtosecond writing in glass, but has a number of advantages including greater flexibility in the writing media and the ability to use low power, inexpensive, continuous-wave lasers. This syst...
