We report on semi-transparent stretchable Ag films coated on a wavy-patterned polydimethylsiloxane (PDMS) substrate for use as stretchable electrodes for stretchable and transparent electronics. To improve the mechanical stretchability of the Ag films, we optimized the wavy-pattern of the PDMS substrate as a function of UV-ozone treatment time and pre-strain of the PDMS substrate. In addition, ...

The wavelet transform (WT) has been developed over 20 years and successfully applied in defect detection on plain (unpatterned) fabric. This paper is on the use of the wavelet transform to develop an automated visual inspection method for defect detection on patterned fabric. A method called direct thresholding (DT) based on WT detailed subimages has been developed. The golden image subtraction...

In this study, we show the effect of various nanoparticle additives on phase separation behavior of a lattice-patterned liquid crystal [LC]-polymer composite system and on interfacial properties between the LC and polymer. Lattice-patterned LC-polymer composites were fabricated by exposing to UV light a mixture of a prepolymer, an LC, and SiO2 nanoparticles positioned under a patterned photomas...

This paper describ_es applications in microfabrication using patterned sel f -assembled monolayers (SAMs) formed by microcontact pr int ing."Microcontact pr int ing (7rCP) is a f lexible new technique that forms patterned SnMs with regions terminated by di f ferent chemical funct ional i t ies (and thus di f ferent physicat and chemical propert ies), in patterns wi th pm dimensions. Patterns of...

Ants are abundant in most of the world's terrestrial environments. They energetic, strong for their size, numerous, and socially cooperative. play many geomorphologically important roles. In particular, they construct mounds subterranean galleries, create patterned ground, a role bioturbation, affect vegetation cover soil properties (such as infiltration rate) influence runoff erosion. also rol...

Microfluidics flow-patterning has been utilized for the construction of chip-scale miniaturized DNA and protein barcode arrays. Such arrays have been used for specific clinical and fundamental investigations in which many proteins are assayed from single cells or other small sample sizes. However, flow-patterned arrays are hand-prepared, and so are impractical for broad applications. We describ...
