Course content

This course is an introduction to micro/nano-machines. Topics include the physics of rubber elasticity, mechanical properties of rubbers, simple theory of polymer gels, theory and application of elastomer actuators, theory and application of gel actuators, and examples of micro/nano-machines using soft materials.

Purpose of class

Functional soft materials have potential as micro/nano-machines. Currently, it has become possible to make small soft materials that are designed for development of micro/nano-machines. In particular, polymeric materials and hydrogels have received much attention because they are unique materials that expand or contract in response to external changes. The goal of this course is to let students understand the mechanical properties of micro/nano-machines and functional materials and to let students understand the states-of-art soft machines, and then discuss together.

Goals and objectives

To understand the deformation mechanism of soft materials.
To understand the principle of operation of soft actuators.
To understand the principle of operation of micro/nano-machines
