Piezoelectric actuators are getting immiscible parts of many important electromechanical and smart systems. Smart systems consist mainly of sensors, actuators, and signal processing units. Actuators are the responding units of many smart systems including those for active vibration and noise control, valve, shutter, focal lens, and many others. Increased demand for actuators with high displacement, high generative force, and quick response time has led to a search for new actuator materials and new designs. In this chapter, first, piezoelectric actuators were compared with magnetically active and thermally active actuators. Second, piezoelectric actuators and their design, especially traditional piezoelectric transducers with newly designed flextensional transducers were compared. Finally, application-related issues have been reviewed.

Powder metallurgy (PM) of biomaterials is still a niche market, but considerable progress in related manufacturing technologies opens up the possibility of participating in the emerging market for medical devices and surgical implants within the next decade. PM technologies like metal injection moulding (MIM) are promising manufacturing routes if large quantities of complex-shaped parts are required. In addition, porous implants or coatings that improve implant fixation by bone ingrowth are preferentially made by PM technologies. In this chapter, the most promising PM routes for biomedical applications are introduced. Challenges and specific properties of implant materials are discussed, which were made starting from titanium, magnesium or Nitinol powders. The potential of PM is demonstrated in four case studies.
