The physics of 3D printing with light

Christophe Moser

The goal of 3D printing is to realize complex 3D structures by locally adding material in small volume elements called voxels - in contrast to successively subtracting material by etching, milling or machining. This field started with optics-based proposal ...

A Sprayable Electrically Conductive Edible Coating for Piezoresistive Strain Sensing

Dario Floreano, Bokeon Kwak, Pietro Rossi

Edible electronics leverages the electronic properties of food-derived materials to deliver safer technologies that can be degraded (or digested) in the environment (or body) at the end-of-life. Sensors will be central to future smart edible robots, and ed ...

Tomographic Volumetric Additive Manufacturing of Silicon Oxycarbide Ceramics

Jürgen Brugger, Christophe Moser, Paul Delrot, Jorge Andres Madrid Wolff, Max Kollep, Georgia Konstantinou, Damien Claude-Marie Loterie, Antoine Vincent Boniface, Lorenz Hagelüken

Ceramics are highly technical materials with properties of interest for multiple industries. Precisely because of their high chemical, thermal, and mechanical resistance, ceramics are difficult to mold into complex shapes. A possibility to make convoluted ...

Utilizing additive manufacturing and mass customization under capacity constraints

Ralf Seifert, Anna Timonina-Farkas, Rachel Agnès Laetitia Rosemonde Marie Lacroix

Additive manufacturing (AM), originally used for prototyping, is increasingly adopted for custom final part production across different industries. However, printing speed and production volume are two barriers for the adoption of AM for product customizat ...

Fabrication of zipping electrostatic actuators incorporating inkjet-printed layers

Herbert Shea, Samuel Rosset, Giulio Grasso

Zipping electrostatic actuators operate by bending flexible electrodes using electrostatic forces. This principle allows the use of a wide range of dielectric and conductive materials. Additive Manufacturing (AM) techniques can be used to fabricate these a ...

Assembling Ni-Fe Layered Double Hydroxide 2D Thin Films for Oxygen Evolution Electrodes

Hubert Girault, Andreas Stephan Lesch, Victor Costa Bassetto, Massimo Rosa

Continuous hydrothermal flow synthesis (CHFS) of Ni-Fe layered double hydroxide (LDH) leads to waterborne dispersions of 2D nanoplatelets in the range of 10-50 nm in lateral size. Conversion of the as-synthesized LDH nanoplatelet dispersion into inkjet pri ...

Gravure printed Ag/conductive polymer electrodes and simulation of their electrical properties

Frank Nüesch, René Uwe Schneider, Jakob Heier

In this paper, some practical issues related to the manufacturing, and design criteria related to the application in devices of a hybrid silver grid/poly (3,4-ethylenedioxythiophene) semi-transparent electrode are discussed. The electrodes are fabricated b ...

Activity-Based Screening of Homogeneous Catalysts through the Rapid Assessment of Theoretically Derived Turnover Frequencies

Matthew Wodrich, Anne-Clémence Corminboeuf, Boodsarin Sawatlon

In homogeneous catalysis, the turnover frequency (TOF) and turnover number (TON) are the most commonly used quantities that experimentally describe catalytic activity. Computational studies, on the other hand, generally yield the ubiquitous free energy pro ...

On Advanced Large-Field Photolithography

Raoul Kirner

The information age we live in today relies on highly integrated devices. They are fabricated with the help of photolithography, the patterning technique at the heart of their production. With the continuous demand for higher integration density to achieve ...
