AC Electric Field Communication for Human-Area Networking

IEICE Transactions on Electronics, 2010
We have proposed a human-area networking technology that uses the surface of the human body as a data transmission path and uses an AC electric field signal below the resonant frequency of the human body. This technology aims to achieve a "touch and connect" intuitive form of communication by using the electric field signal that propagates along the ...

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Measurements of Ionospheric Electric Fields with Antarctic Sounding Rockets S-210JA-24 and 25 (b. Electric Fields and Current System) (Proceedings of the First Symposium on Coordinated Observations of the Ionosphere and the Magnetosphere in the Polar Regions (Part I))

Antarctic Record, 1979
DC and AC (8-110 Hz) electric fields were observed in the auroral ionosphere up to 120 km with spherical double probes on board the sounding rockets S-210JA-24 and 25 at Syowa Station. The rockets passed close to auroras.

Slight Truncation Changes in Iron Oxide Nanocubes Strongly Affect Their Magnetic Properties

Advanced Functional Materials, EarlyView.
Subtle variations in nanoparticle morphology can lead to significant changes in functional properties. An automated shape‐fitting method captures minor differences in corner truncation between iron oxide nanocubes of similar sizes synthesized under identical conditions, revealing pronounced disparities in their magnetic and hyperthermia behavior ...

High Electric Field AC Treatment

Nippon Shokuhin Kagaku Kogaku Kaishi, 2009
1． 交流高電界処理の特徴交流高電界処理とは，イギリスの物理学者ジェームズ・プレスコット・ジュールが見出したジュールの法則（Joule's law）によるジュール熱を利用した加熱技術のひとつである．ジュール熱Qとは，電気抵抗R［Ω］ をもつ物体に，電流 I［A］の2乗をt秒間［s］流したときに発生する熱量として下記に示す（1）式で表すことができる．（1）式 Q＝R×I2×tさらに，オームの法則E［V］＝R×Iを代入することで，（2）式に示すような抵抗に印加する電圧E［V］や電力に比例して加熱温度を変化できることがわかる．（2）式 Q＝E2⁄R×tジュール熱を利用した技術は，内部加熱方式として通電加熱やオーミック加熱と呼ばれ，英語ではelectrical resistance heating ...

Control of Polarization and Polar Helicity in BiFeO3 by Epitaxial Strain and Interfacial Chemistry

Advanced Functional Materials, EarlyView.
In BiFeO3 thin films, the interplay of interfacial chemistry, electrostatics, and epitaxial strain is engineered to stabilize homohelicity in polarization textures at the domain scale. The synergistic use of a Bi2O2‐terminated Aurivillius buffer layer and a highly anisotropic compressive epitaxial strain offers new routes to control the polar‐texture ...
