Method of manufacturing and/or operating deployable structures using hydride material

A method of manufacturing and/or operating a deployable structure, the method comprising:

• providing a sheet material comprising an outer shell structure and a hollow interior, the sheet material having a thickness of 25 μm to 1000 μm;
• placing a hydride material to be converted into hydrogen gas into the hollow interior, the hydride material being in contact with a trigger;
• sealing the outer shell structure;
• and
• converting the hydride material and releasing the hydrogen gas, and expanding and plastically deforming the sheet material by the hydrogen gas,
• 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.
