Abstract
We present a study of an electrical model of electromechanically active carbon-polymer composite (CPC) with carbide-derived carbon (CDC) electrodes. The major focus is on investigation of surface electrode behavior upon external bending of the material. We show that electrical impedance measured from the surface of the CDC-based CPC can be used to determine the curvature of the material and, hence, the tip displacement of a CPC laminate in a cantilever configuration. It is also shown that by measuring surface signals in the process of an actuator’s work-cycle, we obtain a self-sensing collision-detecting CPC actuator that can be considered as a counterpart of biomimetic vibrissae.
Wir präsentieren eine Untersuchung eines elektrischen Modells eines elektromechanisch aktiven Kohlenstoff-Polymer-Komposits (CPC) mit Elektroden aus carbidabgeleitetem Kohlenstoff (CDC). Der Schwerpunkt liegt auf der Untersuchung des Verhaltens der Oberflächenelektroden bei externer Biegung des Materials. Wir zeigen, dass die an der Oberfläche des CDC-basierten CPC gemessene elektrische Impedanz verwendet werden kann, um die Krümmung des Materials und somit die Spitzenauslenkung eines CPC-Laminats in einer Kragarmkonfiguration zu bestimmen. Es wird zudem gezeigt, dass durch die Messung von Oberflächensignalen während des Arbeitszyklus eines Aktors ein selbstsensorischer, kollisionserkennender CPC-Aktor erhalten wird, der als Pendant zu biomimetischen Vibrissen betrachtet werden kann.
