This is about biological and technical hygromorphs, i.e. structures that change shape according to humidity. Next to pine cones, there is also a cool study on wheat awns which drill themselves into the soil just by daily variance of air humidity. Biomimetics would be passively controlled acutators or humidity driven valves in space station to open/close dehumidification devices.

Interesting, but only an abstract... do you have the full paper ?

Not yet. There is also some other nice mechanism of wheat awns and how they use changes in humidity to anchor in soil. Would maybe fit with the above mentioned work of oisin.
