Development of an antagonistically actuated smart joint
Vahidyeganeh, Ali; Şimsek, Görkem Muttalip; Jabeen, Saher; Bebek, Özkan; Yapıcı, Güney Güven (Trans Tech Publications, 2017)Shape memory alloys with their phase transformation properties; have been broadly implemented in smart structures. In this study, a functional design is presented where two wires actuate antagonistically to achieve motion ... -
Discrete-time integral sliding mode control of a smart joint for minimally invasive surgeries
Jabeen, Saher; Yeganeh, Ali Vahid; Şimsek, Görkem Muttalip; Yapıcı, Güney Güven; Abidi, K.; Bebek, Özkan (IEEE, 2016)In this work, a shape memory alloy(SMA) actuator based joint (smart joint) is controlled using a discrete-time integral sliding mode (DISM) control to guide the motion of an active catheter. Controller is designed on the ... -
An in-silico corrosion model for biomedical applications for coupling with in-vitro biocompatibility tests for estimation of long-term effects
Šušteršič, T.; Şimsek, Görkem Muttalip; Yapıcı, Güney Güven; Nikolić, M.; Vulović, R.; Filipovic, N.; Vrana, N. E. (Frontiers Media, 2021-09-07)The release of metal particles and ions due to wear and corrosion is one of the main underlying reasons for the long-term complications of implantable metallic implants. The rather short-term focus of the established ... -
Influence of heat treatment parameters on the functional behavior and corrosion performance of a shape memory wire actuator
Şimsek, Görkem Muttalip; Yapıcı, Güney Güven (Trans Tech Publications Ltd, 2020-04)In the present study, the effect of heat treatment parameters on the functional response, corrosion behavior and microstructural evolution of NiTi shape memory alloys were investigated. Various heat treatment regimes were ...
