在这项研究中,我们调查的形态和机械特性的章鱼吸盘,这可能作为一个模型,为创造新一代的附着装置。章鱼吸盘在潮湿的条件下附着在各种各样的基底上,包括粗糙的表面。这个惊人的特征是由吸盘的组织,这是柔韧的基板轮廓。先前的研究已经描述了一种特殊的内部结构,在吸盘的附着和分离过程中起着重要作用。在这项工作中,我们提出了一个机械特性的组织参与的附着过程中,这是使用微压痕测试进行。我们评估了自然组织的弹性模量和粘弹性参数(E = 10 kPa),并测量了一些人工材料的机械性能,以前已被用于软机器人。生物原型和模仿章鱼吸盘组织的人造材料的这种比较对于设计用于潮湿环境的创新人造吸盘至关重要。我们的结论是,通常用于软机器人的常见弹性体的属性是非常不同的生物吸盘的属性。
In this study, we investigate the morphology and mechanical features of Octopus vulgaris suckers, which may serve as a model for the creation of a new generation of attachment devices. Octopus suckers attach to a wide range of substrates in wet conditions, including rough surfaces. This amazing feature is made possible by the sucker's tissues, which are pliable to the substrate profile. Previous studies have described a peculiar internal structure that plays a fundamental role in the attachment and detachment processes of the sucker. In this work, we present a mechanical characterization of the tissues involved in the attachment process, which was performed using microindentation tests. We evaluated the elasticity modulus and viscoelastic parameters of the natural tissues (E ∼ 10 kPa) and measured the mechanical properties of some artificial materials that have previously been used in soft robotics. Such a comparison of biological prototypes and artificial material that mimics octopus-sucker tissue is crucial for the design of innovative artificial suction cups for use in wet environments. We conclude that the properties of the common elastomers that are generally used in soft robotics are quite dissimilar to the properties of biological suckers.
