A self-powered triboelectric nanosensor for detecting the corrosion state of magnesium treated by micro-arc oxidation.

ABSTRACT: Magnesium (Mg) is frequently used as a biocompatible implantable material in the human body, but real-time detection of its corrosion state is not well understood. Fortunately, previous studies of triboelectric nanogenerators (TENG) as self-driven sensors in many fields have proposed solutions for this problem. In this work, Mg-based TENG was prepared as a self-driven sensor to detect the corresponding corrosion state of Mg treated by micro-arc oxidation (MAO-Mg). Mg-based sheets and polydimethylsiloxane (PDMS) film were used as triboelectric materials. The output of TENG was optimal under 350 V-800 Hz micro-arc oxidation (MAO) treatment of Mg, and the V _oc, I _sc and Q _sc were 48.5 V, 35.3 μA and 44.2 nC, which were respectively 2.42, 3
