Abstract
A method for preventing holding of one or more of a hot liquid or hot food in a utensil. The method including: configuring a utensil portion for holding one or more of a liquid or food to have a first orientation relative to a handle portion when a temperature of a shape memory alloy neck portion connecting the utensil portion to the handle portion is below a transition temperature and changing the orientation of the utensil portion relative to the handle portion to a second orientation when the temperature of the shape memory alloy neck portion is greater than the transition temperature so as to not hold the liquid or food.

A spoon comprising:
- a handle portion;
- and
- a head portion connected to the handle portion, wherein the head portion comprises:
- a concave portion for holding one or more of a fluid or food;
- and
- a shape memory alloy neck portion having one end connected to the concave portion and an other end connected to the handle portion in a first orientation when the shape memory alloy neck portion is at a temperature less than a transition temperature and in a second orientation when the shape memory alloy neck portion is at a temperature greater than the transition temperature, the first orientation being different from the second orientation.
A utensil comprising:
- a handle portion;
- and
- a head portion connected to the handle portion, wherein the head portion comprises:
- a utensil portion for holding one or more of a fluid or food;
- and
- a shape memory alloy neck portion having one end connected to the utensil portion and an other end connected to the handle portion in a first orientation when the shape memory alloy neck portion is at a temperature less than a transition temperature and in a second orientation when the shape memory alloy neck portion is at a temperature greater than the transition temperature, the first orientation being different from the second orientation.
A method for preventing holding of one or more of a hot liquid or hot food in a utensil, the method comprising:
- configuring a utensil portion for holding one or more of a liquid or food to have a first orientation relative to a handle portion when a temperature of a shape memory alloy neck portion connecting the utensil portion to the handle portion is below a transition temperature;
