1. A deployable structure comprising:
a hydride material to be converted into hydrogen gas;
a sheet material encapsulating the hydride material; and
a trigger in contact with the hydride material,
wherein the sheet material has a thickness of 25 μm to 1000 μm and a yield stress,
the hydride material is to release hydrogen gas in response to the trigger, and
the hydrogen gas is to generate a pressure greater than the yield stress of the sheet material such that the sheet material is plastically deformed by the hydrogen gas to have an expanded structure, and
wherein the trigger comprises at least one selected from a thermal trigger comprising a heat source to generate heat, a chemical trigger, and an electrical trigger.
