    摘要： A system to monitor the health of the structure, program product, and associated methods are provided. The system can include multiple health monitoring sensor nodes each including a sensor element connected to or embedded within the body of a structure to be monitored and positioned to monitor parameters of a portion of the body of the structure. The sensor nodes are spatially positioned along the body of structure at related or complementary locations to form a special correlative relationship between sensor nodes. The system can also include a data collector having a transceiver positioned to gather sensed parameter data from each of the sensor nodes. The system can also include a central computer in communication with the data collector and including in memory parameter process program product adapted to analyze the sensed parameter data, correlate the sensed parameter data to infer a state of health of the structure responsive to the correlation, and to detect or otherwise determine a type, severity, and/or location of damage to or incipient failure of the structure.

    摘要： A strain sensor comprises a transmitting element; a receiving element wirelessly coupled to the transmitting element; and a modulating element located on a rotating component, wherein the modulating element modulates the wireless coupling between the transmitting element and the receiving element, wherein the modulation of the wireless coupling is indicative of strain on the rotating component. A method of detecting strain in a rotating component of a rotary machine comprises wirelessly coupling a transmitting element and a receiving element; modulating the coupling with a modulating element located on the rotating component; and calculating the strain in the rotating component based on the modulation of the coupling.

    摘要： A system and method for controlling a tunneling current between a first element and a second element of a micro-electro-mechanical system (MEMS) sensor. The system includes a tunneling current excitation source for providing a tunneling current between the elements and a tunneling current monitor for monitoring a change in the tunneling current responsive to movement of at least one element. The system also includes a positioner for positioning at least one of the elements and a controller in communication with the tunneling current monitor for controlling the positioner to position at least one of the elements at a first spacing between the elements for configuring the system in a referencing mode; and to position the elements at a second spacing for configuring the system in a sensing mode, whereby the system is calibrated with respect to the referencing mode.
