    • The present disclosure relates to a system, for selectively actuating a safety mechanism, to protect against electrical shock, using a transformable material. The system includes the transformable material, being: (1) connectable electrically to an electrical component having an unwanted electrical charge and (2) changeable between a deformed shape and an undeformed shape based on electrical input resulting from the electrical charge at the electrical component. The transformable material is also (3) connected mechanically to the safety mechanism so that change in the transformable material causes movement of the safety mechanism. The transformable material is further (4) configured and arranged in the system to, in response to being exposed to the electrical input, change to its undeformed shape and thereby actuate the safety mechanism.
    • 本公开涉及一种用于选择性地致动安全机构以防止电击使用可变形材料的系统。 该系统包括可变形材料,其为:(1)可电连接到具有不需要的电荷的电气部件,以及(2)基于由电气部件的电荷导致的电输入,在变形形状和未变形形状之间可变化。 可变形材料也是(3)机械地连接到安全机构,使得可变形材料的变化导致安全机构的移动。 可变形材料进一步(4)构造和布置在系统中以响应于暴露于电输入而改变其未变形形状并由此致动安全机构。

    • Remotely engageable and releasable suction cups include a pliable body and an active material in operative communication with the pliable body and configured to create and/or eliminate a partial vacuum through the activation of stiffness or geometry changes in the active material. Suitable active materials include shape memory materials such as shape memory alloys, ferromagnetic shape memory alloys, and shape memory polymers (SMP). A second class of active materials include materials that exhibit a change in at least one attribute when subjected to an applied field but revert back to their original state upon removal of the applied field. Active materials in this category include piezoelectric materials, electroactive polymers (EAP), magnetorheological polymers, and the like.
    • 可远程接合和可释放的吸盘包括柔韧的主体和与柔韧体可操作地连通的活动材料,并被配置成通过激活活性材料的刚性或几何形状的变化来产生和/或消除部分真空。 合适的活性材料包括形状记忆材料,例如形状记忆合金,铁磁形状记忆合金和形状记忆聚合物(SMP)。 第二类活性材料包括当受到施加的场而在至少一个属性中变化但在移除所施加的场时恢复到其原始状态的材料。 该类活性物质包括压电材料,电活性聚合物(EAP),磁流变聚合物等。
