LAMPSe is proud to anounce that Francesco Greco and Matthias Gritzner won the third price in the audience vote of the photo competition held at TU Graz called TU Graz SciPix.

The photos show examples of the everyday research at TU Graz.

Francesco Greco was participating with a photo made by Matthias Gritzner during his bachelor thesis and shows UV ink contained in microfluidic channels made from hydrophilic and hydrophobic LIG.

Liquid Yin&Yang on laser induced graphene
A Yin&Yang symbol is formed by self-guidance and mixing of fluorescent dyes in water on top of a pattern of Laser Induced Graphene with tunable wettability (superhydrophilic/superhydrophobic).

Here you can see video of the microfluidics created with LIG. Fluorescent dyes are deposited on the LIG tracks and are guided down to the bottom because of the hydrophilic properties. At the bottom they come in contact with each other and form a Yin&Yang symbol. The liquid is confined by the hydrophobic LIG on the outside.

LAMPSe is participating in the photo competition held at TU Graz called TU Graz SciPix.

The photos show examples of the everyday research at TU Graz.

Alexander Dallinger is participating with a scanning electron microscope image showing LIG and silver flakes forming a “glacier”.

The everlasting silver glacier
The glacier is formed by silver flakes on mountains of laser-induced graphene, arising from a plastic sheet after scribing with an infrared laser. The glacier is forcing its way down the valley and is connecting the conductive mountains together.

You can participate in the online voting until the 31.05.2021.

New press release by TUGraz about our tattoo electrodes for on-skin biosignal recordings. Here the full text of the press release and some links to press coverage.

Electrodes for long-term monitoring of electrical impulses of heart or muscles were fabricated in the form of temporary tattoos produced using an ink-jet printer.

An international research team involving Institute of Solid State Physics TU Graz together with Italian Institute of Technology, Universitá degli Studi di Milano and Scuola Superiore Sant’Anna in Italy, presents this novel method in Advanced Science.

Paper in Advanced Science (open access)

In the presented method, conducting polymers are printed on commercial temporary tattoo paper, thus producing single or multiple electrode arrangements. The external connections necessary for transmitting the signals are integrated directly in the tattoo. The tattoo electrodes are then applied to the skin like temporary transfer tattoos and can hardly be felt by the wearer. Due to their extreme thinness (< 1 μm), the electrodes can be adapted perfectly to the uneven human skin, and can even be applied to parts of the body where traditional electrodes are not suitable, for instance the face.

Francesco Greco, Assistant Professor at TUGraz and leading the research team, explains:

“With this method we have managed to take a big step forward in further developing epidermal electronics. We are on a direct road to making an extremely economical and simple as well as versatile applicable system which has enormous market potential.”
