Small vs large surface area electrodes.

Large vs small aperture microphone arrays: performance over a large focal area

Microphone arrays offer the potential of obtaining a high-quality speech signal from a remote talker in a noisy, multi-source environment. In many important applications, sources of interest may be located anywhere within a large focal area and thus it is desirable that an array’s performance be uniform over that area. In this paper, simulated and measured results are presented indicating the p...

Production of microporous aluminum oxide electrodes as supports for tethered lipid bilayers of large surface area

A composite electrode made by association of gold and porous aluminum oxide has been used as template for a supported lipid bilayer. An oxide pore size of 170 nm was chosen so that lipid vesicles or proteoliposomes can enter in the pore and cover the pore wall. Triggered vesicle fusion produced a stable and continuous lipid bilayer supported on the large surface area of the honeycomb structure....

Reduced graphene oxide electrodes for large area organic electronics.

Devices based on solution processable organic materials are promising for inexpensive large area electronics on transparent fl exible plastic substrates. [ 1 ] In practice, however, electrodes in organic devices typically consist of vacuum deposited materials that are largely incompatible with this goal. The most widely used transparent electrode for plastic electronics to date is tin-doped ind...

Small area statistics: large statistical problems.

Estimation of body surface area: nomogram vs. mathematical equations.

Body surface area (BSA) has been used in clinical practice to determine dosage of medication and in standardisation of biological parameters such as creatinine clearance, cardiac out put etc. BSA is estimated from measured height and weight, either with a nomogram or using a mathematical equation. There are many mathematical equations in the published literature but many are complex and may not...
