报告简介:固体弹性在自然界和工程学中起着至关重要的作用。通过表面微观工程学、引入刺激响应材料,我们已经开始关于双层结构(皱纹和折痕的弹性不稳定性)的透视研究。在柔性环境(如凝胶、弹性体)中对表面不稳定性的精确控制已经具备应用于生物学和生物医学领域的潜能。我们也在考虑将弹性不稳定性作为未来电子应用的关键功能。我们还开发了一种基于莱顿弗罗斯特效应(Leidenfrost effect )引起的热表面弹性凝胶蹦床的新兴热电发电技术,该技术是在凝胶弹性和莱顿弗罗斯特效应的耦合作用下发生的。热能在自我构建的压电水凝胶系统支持下通过机械运动转化为电能。基于选择不同溶液浓度的凝胶粒子,粒径(4mm-25mm),弹性(0.5kPa-500 kPa),以及诸如质量损失、冲击动力学等的优化体系,我们实现了能够产生3V的转换装置,并基于整合系列装置此能够得到更高的输出量(>30V)。上述这些发现开拓了制造能量采集设备的方法,并且提供了在地热源富集地区的电能采集的潜在解决途径。

Elasticity of solids play a crucial role in many systems in nature and engineering. We have initialised perspective researches on configuring elastic instabilities (wrinkles and creases) of bilayer structures, by micro-engineering the surfaces and/or introducing the stimuli-responsive materials. Exercising precise control over surface instability patterns on soft contexts such as gels and elastomer, has been demonstrated with the potential applications in biological and biomedical contexts. We were also looking into to harness the elastic instability as key function in future electronics applications. We also developed an emerging thermo-electric generating technology based on Leidenfrost effect induced trampolining of elastic gel on hot surface, which was occurred under a coupling effect from the elasticity of gel and Leidenfrost effect. The thermal energy was transferred into electric energy through a Leidenfrost activated mechanical motion, supported by a self-constructed piezoelectric-hydrogel system.
