摘要： Improved microwire strain sensor elements (20, 40, 52, 62) and corresponding methods are provided, which permit accurate, wireless strain monitoring of a variety of structures, including composite structures, through use of a remote detector (28). The sensor elements (20, 40, 52, 62) have amorphous or nanocrystalline metallic alloy microwire cores (22, 48), which exhibit substantially reduced remagnetization responses when the sensor elements (20, 40, 52, 62) are coupled with a structure to be strain-monitored, and the structures are in an unstrained condition. When the monitored structure experiences a strain above a pre-selected threshold value, the microwire cores (22, 48) exhibit substantially different remagnetization responses as an indication that the monitored structure has experienced a strain above a strain threshold or over a range of strain. In use, the strain sensor elements (20, 40, 52, 62) are coupled with a structure to be monitored by application of the sensor elements (20, 40, 52, 62) to a surface of the structure, or by imbedding the sensor elements (20, 40, 52, 62) within the structure, and the coupled sensor elements are periodically interrogated by the detector (28). Preferably, the microwire cores (22, 48) are placed in compression in order to suppress the inherent remagnetization responses thereof by means of a surrounding body (26) or surrounding layers (44, 46) formed of synthetic resin material which shrinks upon curing. When the sensor elements (20, 40, 52, 62) are strained as a result of a strain experienced by the monitored structure, the remagnetization responses of the microwire cores (22, 48) are substantially increased.

摘要： One-time, single-use sensor elements (22, 46) are provided for detecting the occurrence of predetermined conditions such as temperature and elapsed time- temperature. The sensor elements (22, 46) preferably comprise elongated, glass-coated, metal alloy, amorphous or nanocrystalline microwires (30, 48), which can be placed in a position to detect the predetermined condition of interest. An alternating magnetic field detector (28) may be used to continuously or periodically interrogate the sensor elements (22, 46) to determine if the predetermined condition has occurred. In one aspect of the invention, the microwires (30, 48) experience a change in configuration upon the occurrence of the predetermined condition, and have correspondingly different induced remagnetization responses. In another embodiment, a static microwire is provided having an initial bi-stable single domain; when a predetermined time-temperature condition is experienced, multiple domains are established in the microwire, and this can be detected by the detector (28).

摘要： A remote, noncontact temperature determination method and apparatus is provided, which is operable to determine the temperature of a conducting member forming a part of or in operative thermal communication with an object of interest. The method comprises the steps of first inducing a closed vortex eddy current (28) in a conducting member (16, 38, 44) by subjecting the member (16, 38, 44) to a magnetic field, such that the corresponding eddy current magnitude changes exponentially over time. A characteristic time constant of the exponential current magnitude changes is then determined, and this is used to calculate the temperature of the object. The apparatus (24) includes a field transmitting coil (14) coupled with a waveform generator (12) for inducing the eddy current (28), and a field receiving coil assembly (18) which detects the corresponding magnetic field induced by the eddy current (28). Using the invention, temperature determinations can be made which are substantially independent of the relative distance and/or angular orientation between the conducting member (16, 38, 44) and the field receiving coil assembly (18).
