摘要： The present invention relates to a sensing system that, in a preferred embodiment, can be readily integrated into load-lifting structures (such as wings and landing gears) to provide real-time DPHM and obviate/mitigate catastrophic problems. Broadly, the present sensing system combines at least one shim portion with at least one nanogenerator such as a TENG or a PENG. A major advantage of the present sensing system is that it combines in a single structure the following functions: (a) gap management in the component in which the sensing system is installed, (b) collection/storage of measured data for the component in which the sensing system is installed, (c) harvesting/storing energy from operation environment of the component in which the sensing system is installed (e.g., DPHM data when the present sensing system is used for assessment of an aircraft's structural conditions), and (d) wireless transmission of measured data for the component in which the sensing system is installed to a user interface.

摘要： The acoustic fiber transducer has a piezoelectric domain with Young's modulus, Epiezo, and including a non-centrosymmetric crystalline-phase piezoelectric material and inorganic piezoelectric particles. At least one charge collector domain is in electrical connection with the piezoelectric domain and includes an electrically conductive material operative to collect electrical charge generated in the piezoelectric domain. At least one electrical conductor is in electrical contact with the at least one charge collector domain and includes an electrically conductive material operative to transport electrical charge from a charge collector domain to an end of the acoustic fiber transducer as an electrical signal indicative of input acoustic sound pressure on a matrix of textile fibers that includes the acoustic fiber transducer. Outer acoustic energy transmission material has a Young's modulus Etrans, of 0.3 Pa-500 MPa, for matching vibrational modes of the textile fiber matrix. A ratio of Epiezo/Etrans is between about 5 and about 70,000.
