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: Basel Physicists Develop Efficient Method of Signal Transmission from Nanocomponents

Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner. The scientists at the Department of Physics and the Swiss Nanoscience Institute at the University of Basel have published their results in the scientific journal “Nature Communications” together with their colleagues from ETH Zurich.

Electronic components are becoming smaller and smaller. Components measuring just a few nanometers – the size of around ten atoms – are already being produced...

Im Focus: Into the ice – RV Polarstern opens the arctic season by setting course for Spitsbergen

On Tuesday, 19 May 2015 the research icebreaker Polarstern will leave its home port in Bremerhaven, setting a course for the Arctic. Led by Dr Ilka Peeken from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) a team of 53 researchers from 11 countries will investigate the effects of climate change in the Arctic, from the surface ice floes down to the seafloor.

RV Polarstern will enter the sea-ice zone north of Spitsbergen. Covering two shallow regions on their way to deeper waters, the scientists on board will focus...

Im Focus: Gel filled with nanosponges cleans up MRSA infections

Nanoengineers at the University of California, San Diego developed a gel filled with toxin-absorbing nanosponges that could lead to an effective treatment for skin and wound infections caused by MRSA (methicillin-resistant Staphylococcus aureus), an antibiotic-resistant bacteria. This "nanosponge-hydrogel" minimized the growth of skin lesions on mice infected with MRSA - without the use of antibiotics. The researchers recently published their findings online in Advanced Materials.

To make the nanosponge-hydrogel, the team mixed nanosponges, which are nanoparticles that absorb dangerous toxins produced by MRSA, E. coli and other...
