Abstract
In this paper, we investigated a transparent conductive electrode (TCE) that satisfies electrical, optical, and mechanical properties, formed by depositing ultra-thin Ag metal in the form of a random grain boundary with an indium zinc oxide (IZO) layer on a PET substrate. Commonly used ITO electrodes are brittle and difficult.....

Abstract
Thermoelectric energy harvesting has attracted a lot of attention for powering self-powered devices because of the potential to generate energy anywhere with a temperature difference. In particular, a stretchable thermoelectric generator (S-TEG) can be applied to the repetitively moving parts of a machine and even a human body. Herein, we.....

Abstract
Nanostructured transparent conductors have been studied intensively for application to flexible and transparent electronic devices. Among diverse nanomaterials, electrospun nanofibers provide several advantages over other nanomaterials, including a high aspect ratio, uniform distribution, and a facile fabrication process. In the present study, an electrode composed of a core-shell (PVDF)-(Al) structured.....

Abstract
We demonstrated an effective method for fabricating a highly efficient flexible transparent electrode in an oxide/metal/oxide configuration based on an ultrathin Cu film. It exhibited low losses in optical transmittance and electrical conductivity while minimizing current loss due to pinhole-related leakages. The Cu film was developed on a chemically heterogeneous.....

Abstract
Encapsulation of the flexible OLED devices requires a low temperature process and great barrier characteristics against the permeation of water vapor and oxygen. We suggest a new OLED encapsulation method for the flexible OLED device using a sealing line instead of the TFE encapsulation. For the experiments, polyimide substrate with.....

Abstract
The authors report the fabrication of a flexible nickel brazing foil using powdered nickel alloy filler (BNi-2) mixed with an organic binder. The organic binder was composed of a polyacrylic acid polymer, glycol, carbon tetrachloride, and water as a dispersion medium for the powder. The brazing paste so formed was.....

Abstract
To improve the sensitivity of impact sensor modules for automotive air bag systems, we developed a flexible module. The impact sensor was soldered with Sn-3.0Ag-0.5Cu (SAC305) solder on a flexible printed circuit board (FPCB) with an organic solderability preservative (OSP) surface finish. Thermal shock (TS) is one of the test.....
