Crystal adaptronics is an emergent materials science discipline at the intersection of solid-state chemistry and mechanical engineering that explores the dynamic nature of mechanically reconfigurable, motile, and explosive crystals. Adaptive molecular crystals bring to materials science a qualitatively new set of properties that associate long-range structural order with softness and mechanical compliance. However, the full potential of this class of materials remains underexplored and they have not been considered as materials of choice in an engineer's toolbox. A set of general performance metrics that can be used for quantification of the performance of these prospective dynamic materials as micro- and macroactuators is presented. The indices are calculated on two selected representatives of thermosalient solids-materials that undergo rapid martensitic transitions accompanied with macroscopic locomotion. Benchmarking of their performance against extensive set of data for the existing actuator classes and visualization using materials property charts uncover the hidden potential and advantages of dynamic crystals, while they also reveal their drawbacks for actual application as actuators. Altogether the results indicate that, if the challenges with fabrication and implementation in devices are overcome, adaptive molecular crystals can have far-reaching implications for emerging fields such as smart microelectronics and soft microrobotics.

动态晶体作为有机热致动器的全球性能指标。

晶体适应电子学是固态化学与机械工程学交叉学科中的新兴材料科学学科，致力于探索机械可重构，运动和爆炸性晶体的动力学性质。自适应分子晶体为材料科学带来了一系列定性的新特性，这些特性将远程结构秩序与柔软性和机械柔韧性相关联。但是，此类材料的全部潜力仍未得到充分开发，因此尚未被工程师视为工具箱中的首选材料。提出了一组通用性能指标，可用于量化这些预期的动态材料作为微型和大型执行机构的性能。该指数是根据热固性固体的两种选定代表来计算的，这些材料经历了快速的马氏体转变并伴随着宏观的运动。根据现有执行器类别的大量数据对它们的性能进行基准测试，并使用材料特性图表进行可视化，揭示了动态晶体的隐藏潜力和优势，同时它们也揭示了实际用作执行器的缺点。总体而言，结果表明，如果克服了器件制造和实现方面的挑战，自适应分子晶体将对诸如智能微电子学和软微机器人学等新兴领域产生深远的影响。根据现有执行器类别的大量数据对它们的性能进行基准测试，并使用材料特性图表进行可视化，揭示了动态晶体的隐藏潜力和优势，同时它们也揭示了实际用作执行器的缺点。总体而言，结果表明，如果克服了器件制造和实现方面的挑战，自适应分子晶体将对诸如智能微电子学和软微机器人学等新兴领域产生深远的影响。根据现有执行器类别的大量数据对它们的性能进行基准测试，并使用材料特性图表进行可视化，揭示了动态晶体的隐藏潜力和优势，同时它们也揭示了作为执行器实际应用的缺点。总体而言，结果表明，如果克服了器件制造和实现方面的挑战，自适应分子晶体将对诸如智能微电子学和软微机器人学等新兴领域产生深远的影响。
