Highly Flexible Transparent Thin Film Heaters based on Metallic Nanowires

We demonstrate that flexible transparent film heaters (TFHs) with excellent performances can be fabricated from solution-processible metallic nanowire thin films. The TFHs were first deposited on glass and heating performances were monitored at different applied [...]

Tunneling Negative Differential Resistance in Flexible Silicone Graphite Composites

Littlejohn S.D., Nogaret A., Crampin S., University of Bath, UK

Developing flexible electronic materials with the ability to amplify signals is a major challenge for bioelectronics. The next step in developing an active nervous system calls for a flexible electronic material that produces a signal [...]

Flexible Graphene Transistors via Printing Transfer

Chang T.-C., Suh H.-S., Mikael S., Seo J.-H., Nealey P.F., Ma Z., University of Wisconsin-Madison, US

Graphene is an atomic layer material with the characteristics of high mobility, high mechanical strength, transparency and low injection energy barrier with different work function metals. Good transparent electrodes and flexible graphene-based large scale touch [...]

Highly Organized Two and Three Dimensional Singlewalled Carbon Nanotubes-Polymer Hybrid Architectures

Li B., Hahm M.G., Kim Y.L., Kar S., Jung Y.J., Northeastern University, US

We present a new class of highly organized SWCNTs network-polymer hybrid structures, by incorporating horizontally and vertically aligned SWCNTs in desired locations, orientations and dimensions on/inside flexible polymer matrices forming mechanically and electrically robust unique [...]

Thin nanostructured solar cells on metal sheets

Toivola M., Miettunen K., Halme J., Lund P., Helsinki University of Technology, FI

We have studied direct integration of nanostructured, dye-sensitized solar cells (DSC) on industrial sheet metals, used e.g. as building materials. To demonstrate an all-flexible, roll-to-roll producable and mechanically stable DSC, counter electrodes made of platinized [...]

Alcohol vapor sensors using multiple spray-coated SWCNTs

Kim S.J., Choi Y.M., Lee G.W., Kyungnam University, KR

Recent advances in purification, dissolution and dispersion technologies of carbon nanotubes (CNTs) have provided opportunities for the development of various CNT gas sensors[1-2]. Here, we suggest an alcohol vapor sensor using single-walled carbon nanotube (SWCNT)-composites [...]

Controlled Assembly of Highly Density SWNT Networks on a Flexible Parylene-C Substrate

Chen C.-L., Xiong X., Busnaina A., Dokmeci M.R., Northeastern University, US

Single-walled carbon nanotubes (SWNTs) with their attractive properties such as large surface-to-volume ratio, high packing density and long-range order may serve as the potential building blocks for the next generation of nanoscale devices. The integration [...]

Single Walled Carbon Nanotubes based Three Dimensional Flexible Electronics

Makaram P., Selvarasah S., Chen C., Busnaina A., Dokmeci M.R., Northeastern University, US

Single Walled Carbon Nanotubes (SWNTs) with their superior electrical and mechanical properties are very strong candidates for future electronic applications. CMOS electronics are constantly being scaled down to accommodate more devices. Alternative device geometries are [...]

A Novel Process for Flexible Nano Electronic Web Production

Picard G., Schneider J., Seye M-F, Nanometrix Inc., CA

Nanometrix presents a new concept to make monolayers and ultra-thin films for nano electronic web processing. The novel method was designed ex novo to match with today's industrial production line standards. In this process, the [...]
