Hygromnemics: Programmable Material Memory Matter Actuators via Wet Pre‐Constraining

open access: yesAdvanced Materials Technologies, EarlyView.
Humidity‐based pre‐constraining creates hygromnemics‐shape memory matter. From identical biocomposites actuation in dry and wet states is obtained via hygromnemic and hygromorphic actuation, respectively. Hygromnemic actuators present long‐ and short‐term shape memory abilities.
