▎ 摘　　要

NOVELTY - The rotating machine (100) has a casing (102), and a vibration sensor (106) which is configured to provide an output indicative of a condition of the rotating machine. The vibration sensor is provided with a two dimensional (2D) material film that is attached to a surface of the casing. The 2D material film is one of a piezoelectric 2D material film and a strain-sensitive 2D material film. The 2D material film includes graphene. USE - Rotating machine e.g. electric motor. ADVANTAGE - The monitoring can enable the detection of a variety of wear and failure mechanisms and predict lifetime to failure of the rotating machine. The detection in the near-field prevents or limits the chances of any problems that are masked by general mixing of signals in the far-field region. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of monitoring a condition of a rotating machine. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic diagram of a rotating machine. Rotating machine (100) Casing (102) Output shaft (104) Vibration sensor (106) Processor (108)
