Materials for flexible and conformable electronics
Sprache des Vortragstitels:
„The future is flexible“, at least when you believe the short message written on the cover of a Scientific American issue. It simply means that future electronics is expected to be flexible, so that if can be easily rolled or bended. Further thoughts lead to conformable electronic devices, the Morph concept of Nokia may serve as an illustrative example. But how do materials look like that may lead to such electronic circuits? In analogy to our skin, in terms of engineering a simple large area integrated circuit, conformable electronics may be based on entropy elastic materials. Research dates back to early investigations of Röntgen on elastomer actuators in 1880. In the talk it will be outlined how the ingenious combination of energy and entropy elasticity leads to new functionalities. In detail concepts for stretchable piezoelectrics, batteries, optical waveguides and applications of such sytems in spatially resolved position sensing of touch or light signals will be used to illustrate the many possibilities for material research in conformable electronics.
