Conductive Cotton: Scientists Fashioning Electronic Future for Cotton Fiber

31.10.2011
The latest breakthrough in cotton fiber research has scientists envisioning hospital gowns that monitor medical patients and jerseys that test athletic performance, according to Cornell University fiber scientist Juan Hinestroza, co-author of a new study that reveals how everyday cotton can be turned into high-tech fabric.

Hinestroza, professor of fiber science in Cornell’s College of Human Ecology, is part of an international team that developed transistors using natural cotton fibers, gold nanoparticles and polymers. The research builds on his previous work indicating such technology is possible, and will be published in the December 2011 issue of the journal Organic Electronics (currently online at http://bit.ly/spb3Gw).

The innovation represents a significant step forward because it lays the groundwork for creating even more complex devices, such as cotton-based circuits, Hinestroza said. This would allow fabrics to sense body temperature, automatically heat up or cool down, track heart rate and blood pressure in high-risk patients, and monitor the physical effort of high-performance athletes.

“Perhaps one day we can even build computers out of cotton fibers in a similar way as khipus – a recording device based on knots and used by the Inca empire in Peru,” Hinestroza added.

In the study, the first step was aimed at creating a conformal layer of gold nanoparticles over the rough topography of cotton. The next layers were either conductive or semiconductive coatings; the final step was to build the devices. “The layers were so thin that the flexibility of the cotton fibers was preserved,” Hinestroza said.

Two kinds of active transistors, organic electrochemical transistors and organic field effect transistors, were also demonstrated. Both kinds are widely used in the electronics industry as components of integrated circuits, which control the functions of such common devices as phones, televisions and game consoles.

The study represented an interdisciplinary, collaborative effort between fiber scientists from Cornell, physicists from the University of Bologna, electrical engineers from the University of Cagliari and materials scientists from the Ecole Nationale Superieure des Mines de Saint Etienne in France.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
