Conducting Polymer Coatings for Bioelectronic Arthroscopy Probes.

ABSTRACT: This study presents conducting polymer coatings as an effective strategy to enhance the performance of electromechanical arthroscopy probes by significantly reducing electrical equilibration time (the period a surgeon must wait for the probe signal to stabilize before measurement) and improving signal stability. Microelectrodes coated with poly(3,4-ethylenedioxythiophene, PEDOT) reach electrical equilibrium in physiological medium within 10 s, compared to over 2 min for standard electroless nickel immersion gold-based (ENIG) probes and ≈20 s for electrodeposited gold, thereby eliminating impractical delays during arthroscopic procedures. PEDOT coatings also reduce impedance by two to three orders of magnitude at low frequencies (<1 kHz), minimizing sensitivity to hand motion and reducing t
