DESCRIPTION:Elastomers are well known soft materials for different applica
 tions. Elastomers you can often\nfind in our daily life. Traditionally dam
 pers\, sealing or tires are commercial products made of\nelastomers\; tube
 s and implants are typical medical produces. Thermoplastic elastomers\n(TP
 Es) are elastomers\, which can be shaped by thermoplastic processing like 
 extrusion or\ninjection molding. Often those TPEs are used to improve the 
 soft-touch\; for tools or grip\nof a ski-sticks. Soft materials can be fil
 led with inorganic materials to functionalize\; those\nmaterials. Magnetic
  particles are used to achieve magnetorheological dampers. The stiffness\n
 of such dampers can be controlled with a magnetic field. Electrical conduc
 tive fillers can be\nused to achieve piezoresistive sensors or chemical de
 tectors. Over the last twenty years\,\nelectroactive polymer (EAP)\, based
  on elastomer capacitors\, have been investigated. With\nthis kind of EAPs
 \, synthetic muscles where successfully developed. EAPs cannot only used\n
 for actuation\, they can also be used as piezoresitive sensors. To achieve
  those hybrid\nmaterials\, typically inorganic particles are dispersed in 
 a elastomer matrix material. This\nlecture will give an overview on some e
 lastomer based smart materials\, their principles and\nthe drawback of tho
 se developments.
