Abstract: Methods of detecting non-uniformities in a material are described. Such methods can comprise inducing changes in strain state or changing the magnetic moment of a material and measuring magnetic flux leakage that is synchronous with the changes in strain state or magnetic moment, while simultaneously applying an external magnetic field to control the relative magnitude of the magnetic flux leakage.

Abstract: Polymer matrix composites normally consist of spherical or ellipsoidal reinforcement phases distributed randomly throughout the material. The spherical shape of the reinforcing materials reduces the effective electromagnetic properties of the reinforcement. Provided is a composite material which advantageously uses anisotropic electromagnetic properties of high aspect ratio loading using alignment to optimize the extrinsic effective electromagnetic property of the composite. Methods of manufacturing the composite are also described.

Abstract: Provided is a magneto-thermoelectric generator (MTG) device for energy harvesting and more particularly a device for converting waste thermal heat from a photovoltaic cell into mechanical energy and ultimately into electrical energy. Embodiments operate on the principle of thermally-induced switching between open and closed states of a ferromagnetic switch to generate mechanical oscillations that cause strain in a piezoelectric material, resulting in the generation of electrical energy. A structure capable of providing a non-linear restoring force provides mechanical energy to the device, which is a significant improvement over prior art MTG devices employing a linear spring restorative force. The device is also provided as a hybrid photovoltaic (PV)/MTG energy harvester for scavenging heat from photovoltaic cells. The hybrid PV/MTG device is particularly useful for harvesting waste heat to boost power generation, extend flight duration, and provide thermal management aboard HALE platforms.
