This chapter gives an overview of artificial actuators in several physical domains which are applicable for actuation of human mobility.

This chapter will:

• show that power exchange and dynamic characteristics are important aspects to consider when designing actuation systems for human motor function,
• present how paralyzed muscles can be stimulated and therefore used as artificially controlled actuators of the human body,
• give an overview of artificial actuators in several physical domains which are applicable for actuation of human mobility.
