• in the application of digital volume correlation (DVC) [28] in combination with synchrotron radiation-based nano-holotomography enable the study of axially dependent hygroscopic expansion and shrinkage of tissues [29]. This approach overcomes previous limitations related to the use of only affine

• integrate high-resolution computed tomography-based geometries to further elucidate the mechanisms underlying hygroscopic actuation. This integrative approach will bridge experimental findings with computational modeling and advance plant biomechanics and biomimetic transfer. Keywords: digital volume

• correlation (DVC); finite element analysis; hygroscopic bending; plant biomechanics; sorption measurements; Introduction In recent years, the hygroscopic motion of plant structures has attracted increasing attention from researchers and engineers, both for fundamental biological research and bioinspired

• amplitude represents the electromechanical activity [62][63][64]. Similar to the ESM and PFM signal, digital volume correlation (DVC) in combination with in situ X-ray tomography microscopy (XTM) was used by Pietsch et al. [47] for graphite and silicon anodes and by Finegan et al. [48] for a LiMnO2 cathode
