Artificial Muscles

Ionic polymer metal composites (IPMCs) can generate a voltage when physically deformed.

Electroactive polymers (EAPs) respond to electrical stimulation with large deformations. They are dynamic actuators which have attracted attention from an interdisciplinary audience of engineers and scientists. An enabling EAP technology is emerging which attempts to imitate the properties of natural muscle and which, as a result, can perform a unique function in a variety of biologically-inspired robotics applications.

This book reports on the developments of the bipedal walking robot Lucy. Special about it is that the biped is not actuated with the classical electrical drives but with pleated pneumatic artificial muscles.

Design of Artificial Human Joints & Organs is intended to present the basics of the normal systems and how, due to aging, diseases or trauma, body parts may need to be replaced with manmade materials. The movement of the body generates forces in various work situations and also internally at various joints, muscles and ligaments. It is essential to figure out the forces, moments, pressure etc to design replacements that manage these stresses without breaking down. The mechanical characterization of the hard and the soft tissues are presented systematically using the principles of solid mechanics. The viscoelastic properties of the tissue will also discussed. This text covers the design science and methodology from concept to blueprint to the final component being replaced. Each chapter will be a brief overview of various joint/organ replacement systems.
