Micro/Nanopositioning Systems with Piezoelectric Actuators and Their Role in Sustainability and Ecosystems

Micro/nanopositioners based on piezoelectric actuators and their role to preserve the biodiversity of the ecosystem and achieve a sustainable manufacturingsector are presented in this chapter. These positioners are precise at micro/nanometre resolution and have improved and assisted reproduction and somatic cell nuclear transfer, playing an increasingly important role in preserving endangered speciesfrom extinction. Studies suggest these technologies are potentially key factors in our ability to decelerate the degradation of our nature. Further, piezo-actuated micro/nanopositioners are the foundation of add-on accuracy increasing systems, which can return outdated machine tools to service, with minor changes and at aperformance level higher than new machines. This avoids waste of energy and materials, as the outdated machines or their major parts would otherwise be deposedof. In addition, piezo-actuated micropositioners play an essential role in vibrationassisted machining, which reduces energy consumption, increases product quality and extends machine lifetimes.
