DESCRIPTION:Prof. Thomas Speck\, University of Freiburg\, Germany\nPlant B
 iomechanics Group Freiburg\, Botanic Garden\, University of Freiburg\, Sch
 änzlestr. 1\, 79104 Freiburg\, Germany\, Competence Network Biomimetics\,
  Freiburg Centre for Interactive Materials and Bioinspired Technologies (F
 IT) and Freiburg Materials Research Centre (FMF)\nDuring the last decades 
 biomimetics has attracted increasing attention as well from basic and appl
 ied research as from various fields of industry\, architecture and especia
 lly from building construction. Biomimetics has a high innovation potentia
 l and offers the possibility for the development of sustainable technical 
 products and production chains. The huge number of organisms with the spec
 ific structures and functions they have developed during evolution in adap
 tation to differing environments represents the basis for all biomimetic R
 &D-projects. Novel sophisticated methods for quantitatively analysing and 
 simulating the form-structure-function-relationship on various hierarchica
 l levels allowed new fascination insights in multi-scale mechanics and oth
 er functions of biological materials and surfaces. On the other hand\, new
  production methods enable for the first time the transfer of many outstan
 ding properties of the biological role models into innovative biomimetic p
 roducts for reasonable costs. Within the framework of the new Collaborativ
 e Research Centre CRC 141 “Biological Design and Integrative Structures 
 - Analysis\, Simulation and Implementation in Architecture” an interdisc
 iplinary team of biologists\, physicists\, mathematicians\, engineers\, ma
 terial scientists and architects aims to explore the potential of biomimet
 ics for a new smart kind of bioinspired architecture.\n\nAfter a short int
 roduction into the interdisciplinary approach and the different process se
 quences for the development of biomimetic materials for building construct
 ion are presented using examples from CRC 141 and other current R&D-projec
 ts of the Plant Biomechanics Group Freiburg. Main focus is laid on bioinsp
 ired light-weight and damping materials and structures as well as on self-
 x-materials. Examples for light-weight materials with excellent mechanical
  properties are branched fiber-reinforced composite materials and jackets 
 for concrete pillars inspired by branched stems of dragon trees and column
 ar cacti. Examples for structural materials with a high energy dissipation
  capacity include fiber-reinforced graded foams and ultra-thin-layer mater
 ials which are inspired by fruit peels (pomelo\, coconut) and seed coats (
 macadamia). Examples for compliant mechanisms include rod-shaped structure
 s with (self-)adaptive stiffness and hinge-less bending behaviour as well 
 as the bioinspired façade-shading systems flectofin® and flectofold insp
 ired by the bird of paradise flower and the waterwheel plant\, respectivel
 y. Additionally some examples for biomimetic self-repairing materials and 
 structures inspired by various plant organs will be presented.\nLiterature

 urg (PhD 1990) and received 1996 the venia legendi for botany & biophysics
 . After a visiting professorship at the University of Vienna he was offere
 d professorships at the Humboldt-University in Berlin and at the Universit
 y of Freiburg where he acted from 2002 until 2006 associate professor for 
 ‘Botany’ and director of the Botanic Garden. After declining the offer
  of a full professorship and the directorship in general of the Botanic Ga
 rden at the Freie University Berlin he became in 2006 full professor for 
 ‘Botany: Functional Morphology and Biomimetics’.\nHe is speaker of the
  Competence Network Biomimetics\, vice-president of BIOKON international\,
  vice-chair of the Society for Technical Biology and Bionics\, and board m
 ember of the Biomechanics Group of the Society for Experimental Biology\, 
 U.K. Thomas Speck is deputy director of the Freiburg Center for Interactiv
 e Materials and Bio-Inspired Technologies (FIT) and scientific member of t
 he Materials Research Centre Freiburg (FMF).\n\nHe has received several sc
 ientific awards\, is (co-)editor of several scientific books and journals 
 and has published more than 500 scientific articles in the fields of funct
 ional morphology\, biomechanics\, biomimetics\, evolutionary biology and p
 alaeobotany.\n
