Ionic polymer metal composite (IPMC) materials represent a very different approach to building microgripper fingers, in contrast with the standard micromachining approach, where semiconductor fabrication tools are used to create fingers out of polysilicon and related materials. Although there has been substantial activity in modeling IPMCs, both as actuators and sensors, there is a significant gap in the knowledge of this fascinating material. There is no model that predicts the deformation and potential force that the material can produce when it is cut into an arbitrary shape. This is a significant gap in knowledge because it forces applications that use this material to simply guess a ?good? shape for the microgripper fingers. With a model, the design of finger shapes becomes an optimization problem, i.e., more scientific, less ad hoc. As a consequence, the modeling results feed into a robust intelligence concept of a microgripper finger that can perform micromanipulation while it senses its environment in an effective and intelligent fashion. This work will develop a model that computes the shape of an arbitrarily shaped IPMC microfinger given an excitation voltage placed at any location on the finger. This will eventually lead to microfinger designs that produce desired forces and deflections for specific applications.

与标准的微加工方法相反，离子聚合物金属复合材料（IPMC）材料代表了建立微型手指的一种截然不同的方法，该方法使用了标准的微加工方法，该方法使用半导体制造工具从多硅和相关材料中创建手指。尽管对IPMC进行建模，但作为执行器和传感器都有很大的活性，但这种迷人材料的知识存在很大的差距。没有模型可以预测材料将其切成任意形状时可以产生的变形和潜在力。这是知识的重要差距，因为它迫使使用此材料的应用简单地猜测？微流人手指的形状。通过模型，手指形状的设计成为一个优化问题，即更科学的，更少的临时。结果，建模的结果源于微型手指的强大智能概念，该概念可以在有效且聪明的方式感知其环境的同时进行微观渗透。这项工作将开发一个模型，该模型可以计算在手指上的任何位置放置的激发电压，以计算任意形状的IPMC微膜的形状。这最终将导致微芬丁设计产生所需的力和特定应用的偏转。
