摘要： In some embodiments, a variable stiffness structure is provided having constant stiffness material layers and variable modulus material layers arranged in alternating layers. The variable modulus material layers have a material with a changeable elastic modulus in response to an applied energy field so as to allow reversible coupling and decoupling of stress transfer between successive layers of the constant stiffness material layers to provide a change in a bending stiffness of the variable stiffness structure. The constant stiffness material layers may include segmented portions. The constant stiffness material layers may have segmented portions arranged such that successive layers of the plurality of constant stiffness material layers have overlapping segmented portions. The variable modulus material layers may have shaped structures, for example, corrugation, pillars, striations, tubular, or honeycomb configurations.

摘要： An energy harvesting system includes a heat engine and a component. The heat engine includes first and second regions, a conduit, and a shape memory alloy (SMA) material. The conduit extends along a central axis. The SMA material surrounds the conduit and is disposed in one of the regions. The SMA material is radially spaced from a secondary axis that surrounds the central axis. A localized region of the SMA material changes crystallographic phase from martensite to austenite and contract in response to exposure to the first temperature. The localized region of the SMA material also changes crystallographic phase from austenite to martensite and expands in response to exposure to the second temperature. The SMA material rotates about the secondary axis in response to the contraction and expansion of the localized region of the SMA material. Rotation of the SMA material about the secondary axis drives the component.

摘要： A thermomagnetic sensor includes a thermomagnetic probe that includes a ferromagnetic material having a temperature-dependent magnetic permeability characterized by a maximum magnetic permeability value at a temperature below a Curie temperature of the ferromagnetic material. The thermomagnetic sensor further includes an alternating magnetic field source to produce an alternating magnetic field in a vicinity of the thermomagnetic probe to facilitate a measurement of the temperature-dependent magnetic permeability as function of temperature remotely using a thermomagnetic effect. A predetermined relationship between the temperature-dependent magnetic permeability and temperature in a range between the maximum magnetic permeability value and the Curie temperature provides a measurement of a temperature local to the thermomagnetic probe. A battery-temperature measurement system includes the thermomagnetic probe in a battery, a magnetic field coil to apply the alternating magnetic field, and a magnetic permeability measurement apparatus to measure the temperature-dependent magnetic permeability.
