High-resolution 1D moirés as counterfeit security features

Jürgen Brugger, Roger Hersch, Katrin Sidler Arnet, Victor Javier Cadarso Busto, Sylvain Chosson

A moire is an interference pattern that appears when two different periodic structures are overlaid. The image created is extremely sensitive to small variations in the original layers and is thus very interesting for anti-counterfeit protection. We presen ...

Functionalisation of inkjet-printed Organic Field Effect Transistors with odorant binding proteins for the detection of gaseous analytes

Nico de Rooij, Danick Briand, Francisco Molina Lopez, Giorgio Mattana

Inkjet-printing of solution-processable organic materials is a well-known fabrication method utilised to produce electronic devices on flexible substrates. It is especially suitable to realise, with a simple, digital layout design process, large-area devic ...

Spectral Prediction of Juxtaposed Halftones Relying on the Two-by-two Dot Centering Model

Roger Hersch, Vahid Babaei

In a color reproduction workflow, spectral prediction models are useful for establishing the correspondence between colorant sur- face coverages and resulting printed halftone color. Spectral predic- tion models enable calculation of the color gamut and es ...

Silicon nanowires reliability and robustness investigation using AFM-based techniques

Mihai Adrian Ionescu, Montserrat Fernandez-Bolanos Badia, Elizabeth Buitrago Godinez

Silicon nanowires (SiNWs) have undergone intensive research for their application in novel integrated systems such as field effect transistor (FET) biosensors and mass sensing resonators profiting from large surface-to-volume ratios (nano dimensions). Such ...

Nanocomposites based on highly luminescent nanocrystals and semiconducting conjugated polymer for inkjet printing

Jürgen Brugger, Kristopher Pataky

In this work nanocomposites based on organic-capped semiconductor nanocrystals formed of a core of CdSe coated with a shell of ZnS (CdSe@ZnS), with different sizes, and a semiconducting conjugated polymer, namely poly[(9,9-dihexylfluoren-2,7-diyl)-alt-(2,5 ...

Fully Inkjet-Printed Parallel-Plate Capacitive Gas Sensors on Flexible Substrate

Nico de Rooij, Danick Briand, Francisco Molina Lopez

Small fully inkjet-printed gas sensors based on capacitive parallel-plate (PP) structures have been realized on flexible plastic foil and characterized. A gas sensing layer was inkjet-printed between inkjet-printed bottom and top silver electrodes. Compare ...
