摘要： A deformable bi-stable device includes an elastically deformable member having at least two stable configurations and capable of being deformed from a first stable configuration to a second stable configuration, the element passing through an unstable configuration as it is deformed from the first stable configuration to the second stable configuration, and a shape memory polymer layer on or in the elastically deformable member. A method of using this device includes heating the shape memory polymer to a temperature sufficient to reduce the modulus of the shape memory polymer, deforming the deformable member to move from one of the first and second stable configurations to another of the first and second stable configurations, and cooling the device to a temperature sufficient to increase the modulus of the shape memory polymer.

摘要： An airflow control device comprises a body and an active material in operative communication with the body. The active material, such as shape memory material, is operative to change at least one attribute in response to an activation signal. The active material can change its shape, dimensions and/or stiffness producing a change in at least one feature of the airflow control device such as shape, dimension, location, orientation, and/or stiffness to control vehicle airflow to better suit changes in driving conditions such as weather, ground clearance and speed, while reducing maintenance and the level of failure modes. As such, the device reduces vehicle damage due to inadequate ground clearance, while increasing vehicle stability and fuel economy. An activation device, controller and sensors may be employed to further control the change in at least one feature of the airflow control device such as shape, dimension, location, orientation, and/or stiffness of the device. A method for controlling vehicle airflow selectively introduces an activation signal to initiate a change of at least one feature of the device that can be reversed upon discontinuation of the activation signal.

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.
