Robotik Aktüatörde Piezoelektrik Malzemelerin ve Şekil Hatırlamalı Alaşımların Gelişimi

Teknolojik Gelişmeler içinde, yeni bir malzeme grubu olan, fonksiyonel akıllı malzemelere yüksek oranda bir talep vardır. Bu malzemeler geleneksel malzemelerin işlevleri dışında, aktüatör (harekete geçirici), sensör, kontrol sistemleri ve robotik sistemlerinde kullanılırlar ve Bunlardan en önemli iki tanesi; piezoelektrik malzemeler ve şekil hatırlamalı alaşımlardır. Bu derlemede, şekil hatırlamalı alaşımlar (ŞHA) ve piezoelektrik malzemelerin aktüatör sistemlerini inceleyen genel bir bakış içerir. ŞHA lar ve piezoelektrik malzemelerin herbirinin teorik özellikleri detaylı bir şekilde izah edildi. Her iki sistemin farklı çeşitleri değerlendirildi. Robotik alandaki aktüatör tabanlı ŞHA ve pizeoelektrikler geniş bir şekilde incelendi. Bu sistemlerin karşı karşıya kaldığı bazı zayıflıklar ve zorluklar literatürdeki son çalışmalar ile tartışılmıştır.

The Developments of piezoelectric Materials and Shape Memory Alloys in Robotic Actuator

There is a high demand for functional smart materials, especially for new material groups in advanced Technologies. These materialsare used in the actuator, sensor, control systems, and robotic systems, in addition, they can be hybridized with traditional material tocreate a particular function. Piezoelectric materials and shape memory alloys are the most important families among these groups.This review includes an overview of shape memory alloys (SMAs) and piezoelectric material actuator systems in terms of roboticapplications. The theoretical background of each SMAs and piezoelectric materials is well explained. Different types of each systemare interpreted. Using actuator-based SMAs and piezoelectricity in the robotic area is extensively overviewed. Some weaknesses andchallenges facing such systems have discussed through recent studies in the literature.
