He obtained his Ph.D. degree from Harvard University in 2011. After graduating from Harvard, he spent one year as postdoc at MIT. His research is mainly focused on mechanics of materials, especially soft materials and active materials. Shengqiang Cai has received NSF career award in 2016 and Journal of Applied Mechanics Award in 2020.

  

报告摘要:

近年来,软材料被广泛应用于可穿戴设备、软体机器人等众多工程领域。本次讲座中,我将介绍近期对几种不同软材料的研究进展,包含电驱动弹性体、水凝胶、液晶弹性体、离子型凝胶和类玻璃高分子等,并探讨每一种材料的潜在应用价值,及应用相关的基本力学问题。本次讲座还会展示电动软体透镜、智能窗户、离子逻辑门和用于软体机械人的人造肌肉等模型,并讲解与之相关的力学问题,包括电介质弹性体的机电不稳定、液晶弹性体的断裂和疲劳、类玻璃高分子的非稳态裂纹扩展等。

  

In recent years, soft materials have been extensively explored in a myriad of engineering applications such as wearable devices and soft robotics. In the talk, I will present our recent studies of several different soft materials, including electroactive elastomers and gels, liquid crystal elastomers, ionic hydrogels and vitrimers. For each material, I will discuss their potential applications, followed by fundamental mechanics problems associated with the applications.  Prototype demonstrations in the presentation include electroactive soft lens, smart window, ionic logic gate and artificial muscle for soft robotics. The associated mechanics problems are electromechanical instabilities in dielectric elastomers, fracture and fatigue of liquid crystal elastomers and non-steady crack growth in vitrimers.
