Actuators are devices that convert electrical energy into
mechanical work, traditionally used in electrical, pneumatic and
hydraulic systems. As the demand for actuator technologies grows in
biomedical, prosthetic and orthotic applications, there is an
increasing need for complex and sophisticated products that perform
efficiently also when scaled to micro and nano domains.
Providing a comprehensive overview of actuators for novel
applications, this excellent book:
* Presents a mechatronic approach to the design, control and
integration of a range of technologies covering piezoelectric
actuators, shape memory actuators, electro-active polymers,
magnetostrictive actuators and electro- and magnetorheological
actuators.
* Examines the characteristics and performance of emerging
actuators upon scaling to micro and nano domains.
* Assesses the relative merits of each actuator technology and
outlines prospective application fields.
Offering a detailed analysis on current advances in the field, this
publication will appeal to practising electrical and electronics
engineers developing novel actuator systems. Mechanical and
automation engineers, computer scientists and researchers will also
find this a useful resource.
