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.

Crack initiation by contact fatigue
, 1994 La présente thèse est une contribution à la compréhension du phénomène d'écaillage provoque par la fatigue contact. Cette fatigue apparait en dessous d'une surface soumise à un chargement de contact quasi ponctuel, à partir d'une inclusion, site idéal pour l'amorçage de fissures.

Direct Laser Writing of Magnetic Micro Actuators With a Stimulus‐Responsive Compliant Hinge
Advanced Materials Technologies, EarlyView.This study presents a versatile modular design strategy for adaptive 3D microactuators. Using two‐photon‐induced C,H insertion reactions within solid polymer layers, chemically distinct hinge and stimulus responsive materials are patterned in one step. The hinge's properties enable tunable motion, mechanical control, and reconfigurable actuation across
