text: *Demonstration model heat engines have been built which use nitinol wire to produce mechanical energy from hot and cold heat sources. A prototype commercial engine developed in the 1970s by engineer Ridgway Banks at Lawrence Berkeley National Laboratory, was named the Banks Engine.
  *Nitinol is also popular in extremely resilient glasses frames. It is also used in some mechanical watch springs.
  *Boeing engineers successfully flight-tested SMA-actuated morphing chevrons on the Boeing 777-300ER Quiet Technology Demonstrator 2.
  *The Ford Motor Company has registered a US patent for what it calls a "bicycle derailleur apparatus for controlling bicycle speed". Filed on 22 April 2019, the patent depicts a front derailleur for a bicycle, devoid of cables, instead using two nitinol wires to provide the movement needed to shift gears.
  *It can be used as a temperature control system; as it changes shape, it can activate a switch or a variable resistor to control the temperature.
  *It has been used in cell-phone technology as a retractable antenna, or microphone boom, due to its highly flexible and mechanical memory nature.
  *It is used to make certain surgical implants, such as the SmartToe.
  *It is used in some novelty products, such as self-bending spoons which can be used by amateur and stage magicians to demonstrate "psychic" powers or as a practical joke, as the spoon will bend itself when used to stir tea, coffee, or any other warm liquid.
  *It can also be used as wires which are used to locate and mark breast tumours so that the following surgery can be more exact.
  *Due to the high damping capacity of superelastic nitinol, it is also used as a golf club insert.
  *Nickel titanium can be used to make the underwires for underwire bras.
  *It is used in the neckbands of several headphones due to its superelasticity and durability.
  *It is being increasingly used for wire stemmed fishing floats due to its superelasticity.
