“…As well, applications of IPMC materials are presented elsewhere within this book (Oguro,Chapter 13). Osada and colleagues have described many applications for IPMCs, including catheters [Sewa et al, 1998;Oguro et al, 1999], elliptic friction drive elements [Tadokoro et al, 1997], and ratchet-and pawl-based motile species [Osada et al, 1992]. IPMCs have been suggested in applications to mimic biological muscles; Caldwell has investigated artificial muscle actuators [Caldwell, 1990;Caldwell and Tsagarakis, 2000], and Shahinpoor has suggested applications ranging from peristaltic pumps [Segalman et al, 1992] and devices for augmenting human muscles [Shahinpoor, 1996], to robotic fish [Shahinpoor, 1992].…”

“…In order to impose or collect an electric signal across the thickness of the IPMC, both faces of the polymeric membrane must be plated with conductive electrodes. The most used methods to form metallic electrodes onto ionic polymer membranes are based on an ion exchange process and subsequent chemical reduction 5, 21–34. Electrodes are generally realized by using noble metals, such as platinum or gold, though other metals, such as silver, copper or palladium, have been proposed.…”

Spontaneous coronary artery dissection (SCAD) is a rare cause of myocardial ischemia. Multivessel SCAD is much rarer than single vessel involvement and acute coronary syndrome remains the most common clinical presentation of a patient with SCAD. It predominantly occurs in association with atherosclerosis or in the absence of atherosclerosis. We, hereby, present a case of spontaneous multivessel coronary artery dissection in a 35-year-old male patient presenting with chest pain and ventricular tachycardia following emotional stress and discuss the etiology and treatment options.

In order to make EAP actuators technology scalable a design methodology for polymer actuators is required. Design variables, optimization formulas and a general architecture are required as it is usual in electromagnetic or hydraulic actuators design. This will allow the development of large EAP actuators from micro-actuator units, specifically designed for a particular application. It will also help to enhance the EAP material final performance. This approach is not new, since it is found in Nature. Skeletal muscle architecture has a profound influence on muscle force-generating properties and functionality. Based on existing literature on skeletal muscle biomechanics, the Nature design philosophy is inferred. Formulas and curves employed by Nature in the design of muscles are presented. Design units such as fiber, tendon, aponeurosis, and motor units are compared with the equivalent design units to be taken into account in the design of EAP actuators. Finally a complete design methodology for the design of actuators based on multiple EAP fiber/sheets is proposed. In addition, the procedure gives an idea of the required parameters that must be clearly modeled and characterized at EAP material level prior to attempt the design of complex Electromechanical Systems based on Electroactive Polymers.
