Conversely, dynamic deformation of such polyelectrolytes can produce dynamic
electric fields across their electrodes as shown in figure 2.3 (Shahinpoor, 1996c). A
recently presented model by de Gennes et al. (2000) describes the underlying principle
of electrothermodynamics in such ionic polymeric material based upon internal trans-
port phenomena and electrophoresis. IPMNCs show great potential as soft robotic
actuators, artificial muscles, and dynamic sensors in the micro- to macrosize range. In
this section, the generalities of IPMNCs with regard to their manufacturing techniques
and phenomenological laws are presented. Later, we present the electronic and elec-
tromechanical performance characteristics of IPMNCs.
