Abstract
A bearing assembly monitoring system includes a bearing assembly supporting rotation of a rotating member. The bearing assembly includes a fixed portion and rotatable portion. A piezoelectric element is mounted to the fixed portion and generates an electric signal in response to a vibration of the fixed portion. A first transceiver is electrically coupled to the piezoelectric element to receive the electrical signal generated by the piezoelectric element and generate a signal indicative of the vibration of the fixed portion. A gas turbine engine bearing monitoring system and a method are also disclosed.
