    Abstract: A wireless sensor system of a gas turbine engine of an aircraft can include a plurality of wireless sensors distributed within an engine core of the gas turbine engine and an energy harvesting system including one or more energy harvesting devices configured to convert mechanical or thermal energy within the gas turbine engine into electric power and provide the electric power to the wireless sensors. The wireless sensor system can also include a data concentrator coupled to the gas turbine engine. The data concentrator can be configured to receive a plurality of wireless sensor data from the wireless sensors and transmit the wireless sensor data to a communication adapter of the gas turbine engine.
