Dielektrik elastomerler(DE), bir elektrik alanına maruz kalarak büyük deformasyonlar sağlaması, canlı kasına benzemesi ve sensör olarak kullanılabilmesi gibi özelliklere sahip bir polimer çeşididir.Bu çalışmamızda Dielektrik Elastomer Eyleyiciler (DEA)’lardayüksek gerilimde ve farklı frekanslarda meydana gelen sıcaklık değişimlerini araştırılmaktadır.DEA yüzeyinde kare, sinüs, ve üçgen dalga olmak üzere üç farklı elektriksel sinyal uygulanarak malzeme üzerindeki sıcaklık değişimleri test edilmektedir. Sıcaklık değişimleri farklı frekanslara, zamana ve gerilime bağlı olarak termal kamera yardımıyla zamana göre ölçülmektedir. Deneysel çalışmada DEA’lar üzerinde sıcaklıkların oluşması elektriksel sinyaller, gerilim, ortam sıcaklığı ve öngerme gibi etmenlerin etki ettiğini görülmektedir.DEA yüzeyindeki sıcaklık değeri kare dalga formunda yaklaşık 3 Hz de en yüksek değere ulaştığı görülmektedir. Aynı zamanda uygulanan gerilim ile sıcaklık değerleri doğru orantılı olduğu görülmektedir. Yüksek gerilimde sıcaklık değerleri ani yükseldiği için yırtılma gerçekleşmiştir.Bu çalışmanın yeni yumuşak robotlarda, biyomedikal uygulamalarda ve sensörlerde kullanılan DEA’ların yüzey sıcaklıkların dikkat edilmesi açısından önem taşımaktadır.

Dielectric elastomers (DE) are a type of polymer with features such as being exposed to an electric field, providing great deformations, resembling live muscle and can be used as a sensor. In this study, we investigate the temperature changes occurring in high voltage and different frequencies in Dielectric Elastomer Actuators (DEA). Temperature variations on the material are tested by applying three different signals, namely square, sine, and triangular wave, on the DEA surface. Temperature fluctuations are measured according to different frequencies, time and voltage with the help of thermal cameras. In the experimental study, it is seen that factors such as the formation of temperatures on DEAs, electrical signals, voltage, ambient temperature and prestressing. It is seen that the temperature value on the surface of the DEA reaches the highest value at about 3 Hz in square wave form. At the same time, it is seen that the applied voltage and temperature values are directly proportional. As the temperature values increased suddenly at high voltage, tearing occurred. This study is important in terms of paying attention to the surface temperatures of DEAs used in new soft robots, biomedical applications and sensors.
