Abstract

Research and development efforts devoted to electro active polymers (EAPs) are being actively undertaken today due to the numerous advantages of these materials. Moreover, from the viewpoint of world-wide ecological tendencies, renewable and clean energy sources turn the heads of not only researchers. The harvesting or scavenging of ambient energy constitutes an important alternative stage. Among various specifics of EAPs, the point of a high strain level is being considered in order to render EAPs promising materials for actuators or energy harvesters. Piezo devices are usually used for such applications, but when comparing their strain level to that of EAPs, i.e., around 0.2% for piezo elements and easily more than 20% for EAPs, the replacement is highly interesting. Although the Young modulus is smaller than that of ferroelectric materials, the potential storage energy remains higher. EAPs thus show much promise, but so far, the application of high electrical voltages is required and the utilization with other electrical components is limited. To overcome these drawbacks, an intermediate material was developed, exhibiting a large strain at reasonable levels of applied voltage. An investigation of the power harvesting with EAPs was also carried out.
