This article focuses on the fabrication and characterization of stretchable interconnects for wearable electronics applications. Interconnects were screen-printed with a stretchable silver-polymer composite ink on 50-μm thick thermoplastic polyurethane. The initial sheet resistances of the manufactured interconnects were an average of 36.2 mΩ/◽, and half the manufactured samples withstood singl...

We present a novel ‘‘dynamic learning’’ approach for an intelligent image database system to automatically improve object segmentation and labeling without user intervention, as new examples become available, for object-based indexing. The proposed approach is an extension of our earlier work on ‘‘learning by example,’’ which addressed labeling of similar objects in a set of database images bas...

DOI: 10.1002/admt.201600284 fabrication of such materials onto deterministically stretchable designs thus requires reliance on other fabrication techniques. The key focus of the present work was to develop a strategy for combining lithography (thin-film) and screen-printing (thick-film) techniques to realize deterministic, high-performance stretchable devices. Screen printing has been widely us...

Various methods have been developed to fabricate highly stretchable electronics. Recent studies show that over 100% two dimensional stretchability can be achieved by mesh structure of brittle functioning devices interconnected with serpentine bridges. Kim et al show that pressing down an inflated elastomeric thin film during transfer printing introduces two dimensional prestrain, and therefore ...

background haemophilus influenza may cause severe infections in children and adults. the isolation and identification of haemophilus spp. are not appropriately achieved in iran, while numerous infections are ascribed to the different members of this genus. lack of growth factors disks is our main shortage in this regard. materials and methods we obtained haemin (x-factor) from human blood, and ...

The controlled buckling piezoelectric structures can be used for stretchable energy harvesting due to the stretchability and piezoelectricity. In this paper, the ambient environmental excitation is modeled as a bound-limited white noise, and the random analysis is conducted to study the system response of controlled buckling structures. The spatial distribution of the harvestable energy is reve...

Stretchable electronics (i.e., hybrid inorganic or organic circuits integrated on elastomeric substrates) rely on elastic wiring. We present a technique for fabricating reversibly stretchable metallic films by printing silver-based ink onto microstructured silicone substrates. The wetting and pinning of the ink on the elastomer surface is adjusted and optimized by varying the geometry of microp...
