Designing 4D-printed hygromorphs

Mar 01, 2023 (Nanowerk Spotlight) Hygromorphs are materials that can change their shape or size in response to changes in humidity or moisture. They are also sometimes referred to as humidity-responsive materials or moisture-responsive materials. Hygromorphs can be found in nature, such as in the way that some plant structures change shape in response to changes in humidity, or in the way that the wings of some insects can fold up to protect themselves from moisture. Researchers have also developed synthetic hygromorphs that can be used in various applications, such as in…
