Dielectric elastomer actuators [PDF]

, 2001
Stress and strain are introduced as tensor properties. Several theoretical models of stress-strain behaviour are presented, of which the Ogden model is capable of fitting the observed behaviour in the entire range of measurement. Dielectricity is defined, and Maxwell stress is derived.

Chemically Doped Conductive Polymers for Wearable Health Monitoring

Advanced Materials Technologies, EarlyView.
Among conductive polymers, poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), polyaniline (PANI), and polypyrrole (PPy) are the most studied and applied. Chemical doping significantly boosts intrinsic conductivity and mechanical robustness.
