Digital manufacturing of personalised footwear with embedded sensors

Danick Briand, Ryan Mitchell van Dommelen, Rubaiyet Iftekharul Haque, Jaemin Kim

The strong clinical demand for more accurate and personalized health monitoring technologies has called for the development of additively manufactured wearable devices. While the materials palette for additive manufacturing continues to expand, the integra ...

Multiscale 2D/3D microshaping of property-contrast polymer-derived SiCN

Jürgen Brugger, Lorenz Hagelüken

Polymer-derived ceramics are a unique class of materials known for their outstanding properties and versatile applicability. The liquid nature of the precursors allows easy addition of fillers in order to alter the resulting ceramics’ properties. We use a ...

Tensile response of Strain-Hardening Ultra High Performance Fiber Reinforced Concretes under low loading rates and low temperatures

Mohamed Abdul Hafiz

Strain Hardening Ultra High Performance Fiber Reinforced Concretes (SH-UHPFRC) are cementitious materials with exceptional mechanical properties and outstanding durability making them ideal materials for rehabilitation, for the improvement of load carrying ...

EPFL2019

Cellular metallic materials have emerged as a new promising class of materials due to their lightweight porous structures and advanced multi-functional properties. Originally limited to random metallic foams, modern lithography techniques have enabled the ...
