摘要： A shape memory alloy (SMA) valve including an SMA activator component having a shape memory effect to open or close the valve. The SMA valve may be formed from a monolithic sheet of SMA or a wire of SMA. The SMA valve may operate via choking, torsion or lateral movement in one or more dimensions. The SMA valve may include a stage or ball seal and the SMA actuator component may be provided to the stage or ball seal and configured to move the stage or ball seal to seal or open a flow of gas or liquid when the shape memory effect is activated. The SMA valve may include heat sinks to help adjust the temperature of the activator components and/or may include a biasing component to bias the valve in a particular direction.

摘要： A shape memory actuator including: a monolithic shape memory alloy; a shape memory effect (SME) section of the alloy, configured for actuation; a pseudo-elastic (PE) section of the alloy, configured as a sensor for enabling position sensing; and a control system configured to control the actuator by controlling a current through at least the SME section based on the sensor results of the PE section. A method of controlling a shape memory actuator, the method including: applying a predetermined current through the actuator; measuring a first resistance of the SME section; measuring a second resistance of the PE section; calculating an estimated position of the actuator based on the first and second resistances; and adapting the current applied to the actuator based on the estimated position. A method of manufacturing a shape memory actuator, the method including: laser processing; thermomechanically treating; and training the shape memory alloy.
