Freestanding and flexible graphene/polyaniline composite paper was prepared by an in situ anodic electropolymerization of polyaniline film on graphene paper. This graphene-based composite paper electrode, consisting of graphene/polyaniline composite sheets as building blocks, shows a favorable tensile strength of 12.6 MPa and a stable large electrochemical capacitance (233 F g(-1) and 135 F cm(...

Hurwitz, B. J., Zion, M. M., and Promund Obel, I. W. (1974). Thorax, 29, 678-684. Myocardial perforation by flexible Elema endocardial pacing catheters. Myocardial perforation as a complication of permanent endocardial pacing with flexible Elema catheters is described in nine patients. In eight patients pacing failed, but there were no other serious ill-effects. Diaphragmatic pacing occurred in...

Recently, our modern society demands the portable electronic devices such as mobile phones, laptops, smart watches, etc. Such devices demand light weight, flexible, and low-cost energy storage systems. Among different energy storage systems, supercapacitor has been considered as one of the most potential energy storage systems. This has several significant merits such as high power density, lig...

--The purpose of this letter is to study a new ECG measurement by an annular FPC (flexible print circuit) electrode to the arm of the subject. This study attempts to use one FPC patch to measure ECG signals from a single-arm. The measurement system for the ECG circuit and analysis software was built to be able to measure and interpret the very weak and noisy ECG signals from the electrode. To c...

We describe a transparent and flexible field-effect transistor (FET) made from graphene and single-walled carbon nanotubes (SWNT) hybrid system. Graphene and vertically aligned SWNTs simultaneously grown by alcohol catalytic chemical vapor deposition (ACCVD) were employed as channel and source-drain electrode, respectively. Gate electrode was also made of SWNTs separated with a thin poly(vinyl ...

A methylene-blue (MB)-labeled molecular beacon junction probe allows for a signal-on electrochemical detection of nucleic acids via target recycling using endonucleases. Electron transfer is reduced when the MB is intercalated in the stem of the molecular beacon, but then electron transfer from MB to a gold electrode is enhanced upon cleavage of the junction probe due to increased probability o...

Hierarchical core-shell NiCo2O4@NiMoO4 nanowires were grown on carbon cloth (CC@NiCo2O4@NiMoO4) by a two-step hydrothermal route to fabricate a flexible binder-free electrode. The prepared CC@NiCo2O4@NiMoO4 integrated electrode was directly used as an electrode for faradaic supercapacitor. It shows a high areal capacitance of 2.917 F cm(-2) at 2 mA cm(-2) and excellent cycling stability with 90...

We report on an indium-free and cost-effective Cu2O/Cu/Cu2O multilayer mesh electrode grown by room temperature roll-to-roll sputtering as a viable alternative to ITO electrodes for the cost-effective production of large-area flexible touch screen panels (TSPs). By using a low resistivity metallic Cu interlayer and a patterned mesh structure, we obtained Cu2O/Cu/Cu2O multilayer mesh electrodes ...
