From active tuning of single cell stiffness towards multipurpose (re)programmable mechanism – Presented by Florent Cosandier, CSEM

From active tuning of single cell stiffness towards multipurpose (re)programmable mechanism – Presented by Florent Cosandier, CSEM at the 3rd edition of 4D Printing & Meta Materials Conference, which takes place on 18 April 2018 at Brightlands Chemelot Campus in Sittard-Geleen, The Netherlands.

Metamaterials linked to Additive Manufacturing and to Topology Optimization can lead to profound change in the way mechanisms and even materials are designed. Our goal is to conceive and manufacture a structured material, subdivided into cells, whose stiffness can be is (re)programmable. The result is a metamaterial that is a universal (re)programmable mechanism. Examples of application fields include adaptive optics, launch lock mechanisms and haptics. This presentation will show the great potential of such (re)programmable mechanisms and illustrate it through some proof-of-concept devices, while outlining the underlying philosophy of this approach.

About Florent Cosandier
Born in 1984, Dr Florent Cosandier grew up in Neuchâtel, Switzerland. He obtained his master’s degree in engineering from the Swiss Federal Institute of Technology (EPFL) in 2007, after completing his studies during the master thesis at the Chinese University of Hong Kong (CUHK). In 2013, he obtained his PhD at the EPFL, for which he was awarded the Prix Omega scientific award. He then joined the Swiss Federal Institute of Metrology (METAS) for a postdoctoral position, where he developed precision mechanisms for the new Swiss watt balance. In 2014, he joined the Swiss Center for Electronics and Microtechnology (CSEM) in Neuchatel, Switzerland, where he currently develops precision flexure mechanisms for watchmaking, aerospace and metrology applications. He is involved in the design and testing of various high precision mechanisms, as well as in additive manufacturing, metrology and watchmaking projects, as well as in two ESA projects. In 2017, he published in collaboration with three coauthors a book entitled: “The Art of Flexure Mechanism Design”.

4D Printing ConferenceAbout the 4D Printing & Meta Materials Conference
The 3rd edition of the 4D Printing & Meta Materials Conference will take place on April 18, 2018, at Brightlands Chemelot Campus in Sittard-Geleen, The Netherlands. At the same location, on April 17, 2018, the 3D Printing Materials Conference and the 3D Printing Design & Engineering Conference will be held.

Making and utilizing new materials to improve our life is a defining feature of mankind. We moved on from the stone age, to the bronze age, to the age of silicon and plastic. Now we are at the edge of a new episode, where technological breakthroughs allow us to create, investigate and dream of a total new range of structured forms of matter.

Two fields emerge strongly:

  1. 4D Printing offers a streamlined path from idea to full functionality.
  2. Mechanical metamaterials are structured materials with mechanical properties defined by their structure rather than their composition.

These are highly promising disciplines which develop in a synergistic manner, and which aim at creating entirely new forms of matter, which will lead to applications that have not yet been conceived.

The 4D Printing & Meta Materials Conference will not only cover the academic results but will show how designers and engineers will see future applications and new markets.

Who should attend? Engineers; Designers; Material researchers; Material producers; Academics; anyone who sees potential in 4D Printing and Meta Materials
