EAGER:(Early-Concept Grant for Exploratory Research)- Loss-Free Energy Storage and Transition Due to Nature's Miracle Protein ResilinMechanical systems with programmable elastic properties to permit loss-free transmission or storage of mechanical energy are the ultimate dream of engineers. Nature offers readily available model systems found in the cuticle of insects. It is assumed that the highly elastic protein resilin- in specific cuticle places leads to optimal energy storage. The central hypothesis is that not only the material itself but also the positioning of elastic elements result in a nearly loss-free energy transport. The objective of the proposed project is to explore the static and dynamic properties of highly elastic cuticle with advanced nanomechanical testing methods. The local probing of the individual elastic elements inside the cuticle under various conditions is original and will reveal fundamentally new information that is not accessible with any other method. Understanding the mechanical behavior of resilin and the optimal positioning in the insect cuticle will lead to the design of new rubberlike polymers and novel micromechanical spring-systems with extraordinary low energy loss. The expected findings will result in a new quality of micro and nanomechanical systems, which will be superior to any other existing solutions and have a wide range of applications. Energy efficient locomotor systems are of high interest in the construction of minuscule robots for operational use in areas dangerous for human safety and health. Engineering systems based on the example of the excellent flight maneuver of the dragonfly or the efficient jumping mechanism of grasshoppers will have, without any doubt, similar impact as surfaces designed after the LOTUS effect.

EAGER:（探索性研究的早期概念资助）-自然奇迹蛋白质弹性的无损耗能量存储和转换具有可编程弹性特性的机械系统允许无损耗传输或存储机械能是工程师的终极梦想。大自然在昆虫的角质层中提供了现成的模型系统。据推测，高弹性蛋白弹性蛋白-在特定的角质层位置导致最佳的能量储存。中心假设是，不仅材料本身，而且弹性元件的定位导致了几乎无损失的能量输运。本项目旨在利用先进的纳米力学测试方法研究高弹性角质层的静态和动态特性。在不同条件下对角质层内单个弹性元件的局部探测是原始的，将揭示任何其他方法无法获得的基本新信息。了解弹性蛋白的力学行为及其在昆虫角质层中的最佳定位，将有助于设计出具有超低能量损失的新型类橡胶聚合物和新型微机械弹簧系统。预期的研究结果将导致微纳米机械系统的新质量，这将优于任何其他现有的解决方案，具有广泛的应用范围。高效节能的运动系统在微型机器人的建造中引起了人们的高度兴趣，这些微型机器人可以在危及人类安全和健康的地区进行操作。毫无疑问，以蜻蜓出色的飞行机动或蚱蜢高效的跳跃机制为基础的工程系统，将与根据LOTUS效应设计的表面产生类似的影响。
