Plasmonic Structural Colors For Plastic Consumer Products

Højlund-Nielsen E., Clausen J., Thamdrup L.H., Zalkovskij M., Højlund-Nielsen E., Nielsen T., Mäkelä T., Ahopelto J., Mortensen N.A., Kristensen A., Technical University of Denmark, DK

Today colorants, such as pigments or dyes, are used to color plastic-based consumer products, either as base for solid colored bulk polymer or in inks for surface decoration. After usage, the products must be mechanically [...]

Effective Multistep Exciton Delivery Through DNA-based Photonic Wires

Spillmann C.M., Buckhout-White S., Ancona M.G., Cunningham P.D., Melinger J.S., Goldman E.R., Medintz I.L., Naval Research Laboratory, US

Energy manipulation at the nanoscale is a key requirement to develop next-generation nanotechnologies ranging from biosensing to light harvesting, yet the design rules of these nanoscale systems must first be optimized to accomplish their intended [...]

230 fold fluorescence enhancement by 3D Rhodamine B coated polystyrene photonic crystals

Eftekhari E., Li Q., Li X., Cole I.S., Li Q., Li X., Griffith University, AU

We report a 230-fold fluorescence enhancement with fluorescent polystyrene based three-dimensional (3D) colloidal photonic crystals (F-CPhCs) that can be readily fabricated over large areas. A simple and reproducible method was developed to synthesise novel fluorescent [...]

3D laser writing in-line process for the rapid fabrication of flexible electronic devices

Dubourg G., Marjanović S., Zlebic C., Matovic J., Crnojević Bengin V., Biosense Center, RS

In this work, we present for the first time a new approach of a 3D direct laser writing which allows the patterning of several layers in a single step by adjusting the parameters of the [...]

Transparent, Scalable, and Flexible Piezoelectric Pressure Sensors

Vishniakou S., UC San Diego, US

We present a pressure-sensitive ZnO thin-film transistor (TFT) as a potential technology for next-generation touchscreen. We discuss the properties of our devices and propose a structure that could be used to create transparent, scalable, and [...]

Wearable and flexible electronic devices: Market forecasts 2015-2025

Zervos H., IDTechEx Inc, US

Wearable technology mainly concerns devices and apparel. With a wide range of products, from glasses and other headgear to arm, wrist, leg and footwear, skin patches and even jewelry, the device business is already large, [...]

Room-temperature printing of thin-film devices for flexible electronics

Minari T., Kanehara M., National Institute for Materials Science (NIMS), JP

We have established 'Room-Temperature Printed Electronics (RTPE)' as the new fabrication method for thin-film electronic devices, which can be carried out under ambient atmospheric condition at room temperature without application of heat. Thermal damage is [...]

Engineering nanoinks and photonic manufacturing for printable electronics

Hu A., University of Tennessee, US

We have developed various nanoinks, including silver nanowires, silver nanoplates, Cu-Ag core-shell nanoparticles, graphene oxide and graphene. Gram level nanoplates are successfully synthesized through a polymer controlled hydrothermal growth. Core-shell structures are synthesized through a [...]

Design and Evaluation of a Highly Stretchable and Conductive Thin Film for Tactile Sensors

Sun Y., Zhou D., Bai J., Wang H., Cao J., Univeristy of Minnisota Duluth, US

Keeping good conductivity at high stretching strain is one of the main requirements for the design of flexible electronic devices. The elastic nature of siloxane-based elastomers enables many innovative designs in wearable sensor devices and [...]

Wafer-Scale Planarization using Location Specific Gas Cluster Ion Beam (GCIB) in Advanced CMOS Logic Technology

Moon Y., Qin L., Koli D., Snow C., GlobalFoundries, US

In sub-14nm advanced CMOS logic technology, controlling wafer-scale planarization or uniformity became tremendously critical. This is mainly due to the CMOS integration scheme where chemical mechanical polishing (CMP) is used to create the transistor gate. [...]
