Nanoporous tripeptide crystals mechanically deform upon water evaporation due to the strengthening of the water hydrogen bonding inside the pores, which causes the distortion of the surrounding supramolecular network, creating stresses that extend through the crystal lattice and result in actuation.

由水氢键驱动的执行器

由于孔内水氢键的加强，纳米多孔三肽晶体在水分蒸发时发生机械变形，这会导致周围超分子网络的变形，产生延伸穿过晶格并导致驱动的应力。
