The World’s First Sterilizable Flexible Organic Transistors

02.04.2012
The University of Tokyo (Tokyo, Japan) and the Japan Science and Technology Agency (JST) announced on 6th March 2012 that an international research team led by Professor Takao Someya has succeeded in manufacturing the world’s first flexible organic transistor on a polymeric film.

This organic transistor is robust under high temperature medical sterilization processes. The high thermal stability of the gate layer was confirmed by a cooperative structural analysis using a synchrotron radiation beam at Brookhaven National Laboratory’s (BNL) Synchrotron Light Source (NSLS).

The study is reported in BNL News and published online in Nature Communications on 6th March 2012*. This research is carried out as an ERATO Project of JST.

In a serious aging society with a declining birth rate, electronics are increasing their importance in health and medical areas. On this background, the expectation is getting higher on a flexible organic transistor, which is a soft electronic switch.

Manufacturing of a flexible transistor on a bio- compatible polymeric film is not too difficult. For practical implementation, however, high temperature stability and low operating voltages are challenging problems with the best match of its softness and bio-compatibility.

The international research team has succeeded in manufacturing an organic transistor on a polymeric film that has a high thermal stability up to 150°C or higher and the low driving voltage of 2 V with high mobility of 1.2 cm2V−1s−1 at the same time. The new type organic transistor can be sterilized in a standard sterilization process (150°C heat treatment).

The key technology to realize the heat resistant organic transistor with low driving voltage is the development of a new insulating film comprising an ultra-thin (--2 nm) and densely packed layer named self-assembled monolayer (SAM).

Research team seems to expect such applications as long implantable devices and some medical devices like a smart catheter, and thin film medical sensors.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
