Inductively Coupled Multifunctional Carbon Nanotube-Gold Nanocomposite Sensors

摘要

A layer-by-layer nanocomposite thin film passive wireless strain and pH sensor is proposed. By controlling polyelectrolyte species during fabrication, electromechanical (e.g. strain) and electrochemical (e.g. pH) transduction mechanisms can be encoded in these thin films. Furthermore, a conductive carbon nanotube-gold thin film is patterned into a coil antenna to realize true wireless inductive coupling capabilities.
