Dehnungsmessung an piezoresistiver polymerabgeleiteter Keramik

Abstract

Polymer-derived ceramics with piezoresistive properties consist of siliconoxycarbide nanocomposites (SiOC/C). In contrast to commercial (piezo-) resistive materials, SiCO/C nanocomposites have high pressure sensitivity and a high temperature resistance over 400°C. Because of its ceramic properties, SiOC/C can be modeled as a volume body and therefore does not require any additional spring elements. By varying the volume percent of the segregated carbon x
