A new brochure covers medical applications using piezoceramic actuators and components. Advantages of piezomotors and actuators over traditional motion-control components include sterile/high bake-out temperatures; no lubricants required; nonmagnetic principle (MRI, etc.); vacuum compatible; smaller, higher force; faster response; and direct linear motion without conversion losses.
