Journal ArticleDOI

Mechanical flexibility of transparent PEDOT:PSS electrodes prepared by gravure printing for flexible organic solar cells

Chung-Ki Cho, +5 more
- 01 Dec 2011 - 
TL;DR: In this paper, a flexible poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) films printed onto a flexible PET substrate using a gravure printing method was investigated using a lab-made bending test system.
Journal ArticleDOI

Development of micro-heaters with optimized temperature compensation design for gas sensors.

Woo-Jin Hwang, +4 more
- 01 Mar 2011 - 
TL;DR: A novel design of a poly-Si micro-heater is proposed to improve the uniformity of heat dissipation on the heating plate and shows a short response time of less than 20ms, indicating a very high efficiency of pulse driving.
Journal ArticleDOI

Flexible supercapacitor fabrication by room temperature rapid laser processing of roll-to-roll printed metal nanoparticle ink for wearable electronics application

Junyeob Yeo, +17 more
- 15 Jan 2014 - 
TL;DR: In this article, a rapid and low-temperature laser annealing process of roll-to-roll (R2R) printed metal nanoparticle (NP) ink on a polymer substrate was introduced as an alternative to the conventional thermal annesaling process using expensive and time consuming lengthy furnace.
Journal ArticleDOI

Highly flexible and stretchable carbon nanotube network electrodes prepared by simple brush painting for cost-effective flexible organic solar cells

Da-Young Cho, +3 more
- 01 Jan 2014 - 
TL;DR: In this paper, a brush-painted carbon nanotube (CNT) network electrode was developed by a simple brush-painting method for the production of cost effective flexible organic solar cells (FOSCs).
Journal ArticleDOI

Package-level integrated antennas based on LTCC technology

Sang-Hyuk Wi, +6 more
- 07 Aug 2006 - 
TL;DR: In this article, a stacked patch antenna is designed and integrated in a package using a low temperature co-fired ceramic process, and the antenna is mounted on a 20×20 mm2 ground plane to miniaturize the volume of the system.
