An actuator comprising an SMA element and a thermally responsive element that adjusts bias stress improves high ambient temperature operation. 1. An actuator comprising an SMA element and a thermally responsive element that adjusts bias stress.2. An actuator according to claim 1 , wherein the thermally responsive element comprises a member selected from the group consisting of active materials having a high coefficient of thermal expansion claim 1 , shape-memory alloys claim 1 , and bimetallic elements. The present disclosure relates to control of actuators operating with shape-memory alloys.This section provides background information related to the present disclosure that is not necessarily prior art.Shape memory alloy (SMA) actuators are used for a wide range of applications. One typically application for SMA actuators is to perform limited displacements which generate work. In such displacement applications, the SMA actuator is typically in the form of a wire that transforms linear motion into incremental relative motion. When applying a current to the cold (low temperature or martensitic state) shape memory alloy (SMA) wire the temperature rises until the transformation temperature is reached (high temperature or austenite state) and due to a crystalline restructuring of the material, a contraction occurs. With such a contraction, force or torque is thus generated. However, it is to be appreciated that after the contraction, the SMA wire does not reset itself and therefore a counterforce has to bring the SMA wire into its original position. As the SMA wire cools it returns to its low temperature or martensitic state. The temperature at which the shape memory alloy remembers its high temperature form, referred to as the phase transformation temperature, can be adjusted by applying stress and other methods. In nickel-titanium shape memory alloys, for example, it can be changed from above about 100° C. to below about −100° C.SMA actuators can be slow to reset or ...

Temperature activated unfolding structure for drinking straws and other enclosed containers

Номер: US20220073234A1
Автор: Hale, III RICHARD THOMAS
Принадлежит:

A machine for opening drinking straws and/or other enclosed containers using temperature changes. In the drinking straw variety, the straw is made in part or in full by Nitinol (also known as nickel titanium), Shape Memory Material, or similar such material that allows for the change in the straw's shape (known as the parent phase) in the elevated temperature of a dishwashing machine or similar machine using the Nitinol's or Shape Memory Material's reversible solid-state phase change (known as a martensitic transformation). When the straw is returned to room temperature, the straw closes to its original shape (known as its daughter phase) allowing it to be used as a standard straw. The container variety uses the same method but adapts it for container shapes. This phase change allows for lodged materials in the straw and/or container to be easily dislodged by the object opening in the dishwasher. 1.

With applications such as soft robotics being severely hindered by the lack of strong soft actuators, the invention provides a new soft-actuator material—Electrically Actuated Hydraulic Solid (EAHS) material—with a stress-density that outperforms any known electrically-actuatable material. One type of actuator is fabricated by making a closed cell that acts as highly paralyzed version of a standard paraffin actuator. Each cell exhibits microscopic expansion, which is summed to produce macroscopic motion. The closed cellular nature of the material allows the system to be cut and punctured and still operate. It can be produced in a lab or industrial scale, and can be formed using molding, 3D printing or cutting. 1. An Electrically Actuated Hydraulic Solid (EAHS) material comprising:a phase change material (PCM);an elastomeric polymer material;a conductive material, the phase change material and the conductive material embedded within the elastomeric polymer material forming a conductive elastomeric structure, wherein the PCM undergoes a phase change as controlled by the conductive material to vary an internal pressure and actuate the structure.2.
