Controlling Epileptiform Activity with Organic Electronic Ion PumpsAuthorsAdam Williamson, Jonathan Rivnay, Loïg Kergoat, Amanda Jonsson, Sahika Inal, Ilke Uguz, Marc Ferro, Anton Ivanov, Theresia Arbring Sjöström, Daniel T. Simon, Magnus Berggren, George G.

In treating epilepsy, the ideal solution is to act at a seizure's onset, but only in the affected regions of the brain. Here, an organic electronic ion pump is demonstrated, which directly delivers on-demand pure molecules to specific brain regions. State-of-the-art organic devices and classical pharmacology are combined to control pathological activity in vitro, and the results are verified with electrophysiological recordings.

A Tattoo That Monitors Your Sweat [VIDEO]

A Tattoo That Monitors Your Sweat [VIDEO] | 21st Century Innovative Technologies and Developments as also discoveries, curiosity ( insolite)... | Scoop.it
Researchers at UCSD at developing technology that will create a tattoo that monitors your sweat to provide an assessment of metabolic health.

 

A team at the University of California-San Diego are looking into sensors applied to the skin, much like a temporary tattoo. In the journal Analytical Chemistry, researchers explain these thin strips of adhesive can monitor an athlete’s chemical balance to gauge their physical activity.

So long, transistor: How the 'memristor' could revolutionize electronics - CNN.com

So long, transistor: How the 'memristor' could revolutionize electronics - CNN.com | 21st Century Innovative Technologies and Developments as also discoveries, curiosity ( insolite)... | Scoop.it

From electrons to ions
Simply put, the memristor could mean the end of electronics as we know it and the beginning of a new era called "ionics".

The transistor, developed in 1947, is the main component of computer chips. It functions using a flow of electrons, whereas the memristor couples the electrons with ions, or electrically charged atoms.

In a transistor, once the flow of electrons is interrupted by, say, cutting the power, all information is lost. But a memristor can remember the amount of charge that was flowing through it, and much like a memory stick it will retain the data even when the power is turned off.

This can pave the way for computers that will instantly turn on and off like a light bulb and never lose data: the RAM, or memory, will no longer be erased when the machine is turned off, without the need to save anything to hard drives as with current technology.

But memristors have another fundamental difference compared with transistors: they can escape the boundaries of binary code.

Physicists discover how to change the crystal structure of graphene

Physicists discover how to change the crystal structure of graphene | 21st Century Innovative Technologies and Developments as also discoveries, curiosity ( insolite)... | Scoop.it
A University of Arizona-led team of physicists has discovered how to change the crystal structure of graphene, more commonly known as pencil lead, with an electric field, an important step toward the possible use of graphene in microprocessors that would be smaller and faster than current, silicon-based ...


Unlike silicon transistors used now, graphene-based transistors could be extremely thin, making the device much smaller, and since electrons move through graphene much faster than through silicon, the devices would enable faster computing.

In addition, silicon-based transistors are being manufactured to function as one of two types – p-type or n-type – whereas graphene could operate as both. This would make them cheaper to produce and more versatile in their applications.
