Conference Paper
Full-text available
Since continuum robots are applicable in many areas, including industry and medicine, research interest in this field is continuously increasing. A crucial aspect to effectively control their complex motion is the type of actuators. Common solutions are characterized by bulky driving units placed at the base of the robot. Although these solutions a...
Conference Paper

To determine the lifespan of a system, the lifespan of all parts as well as the interaction of the parts as a system must be known. Accordingly, in systems where shape memory alloy (SMA) wires are used as actuator elements, their lifespan must be determined as well. Therefore, a test bench to determine the lifespan of SMA wires is needed. Since the...
Conference Paper
Full-text available
For repeated actuation in shape memory alloy (SMA) actuators, a restoring force is needed to return to the initial starting position after activation. Therefore, SMA wires are often coupled with mechanical springs, which lengthen said wires again after activation through heating and resulting contraction. In more advanced SMA actuation systems a se...
Conference Paper
Full-text available
Today, Nickel-Titanium (NiTi)-based shape memory alloy (SMA) wires are already used in a wide range of commercial actuator applications. The combination of their unique properties, such as their high energy density as well as their biocompatibility provides a broad range of applications. The former in particular allows for designing light-weight ac...
Conference Paper
Full-text available
In this paper, the development process of a shape memory alloy (SMA) driven pinch valve is proposed. The features of SMA actuator wires like small installation space, small weight, and the high energy density, allow for designing compact systems with high force outputs. A functional prototype is presented, allowing for closing forces of up to 250 N...

Continuum robots find applications in variety of fields such as medicine, industry, and security. Suitable actuators represent a critical aspect to effectively control their complex motion. Common solutions are characterized by bulky driving units placed at the robot base. Despite this design allows preserving the lightweight nature of the active p...
Conference Paper
Full-text available
In this paper, a shape memory alloy (SMA) based, multifunctional smart implant for improved bone fracture healing is presented. In contrast to conventionally used medical implants such as intramedullary nails or bone plates supporting a fractured bone in a passive way, the developed smart implant has on the one hand the ability to work as a common...
Conference Paper
Full-text available
Due to their unique manipulation capabilities, continuum robots find applications in a variety of different areas, such as medical technology or maintenance and repair. When working with continuum robots, it is often necessary to bend the structure according to complex shapes. This is commonly achieved by arranging several individual modules in ser...
Conference Paper
Full-text available
As a smart material thermal shape memory alloys (SMAs) feature actuator behavior combined with self-sensing capabilities. With their high energy density and design flexibility they are predestined to be used in soft robotics and the emerging field of morphing surfaces. Such shape changing surfaces can be used for novel human-machine interaction (HM...
Conference Paper
Full-text available
Continuum robots are inspired by biological trunks, snakes and tentacles. Unlike conventional robot manipulators, there are no rigid structures or joints. Advantageous is the ease of miniaturization combined with high dexterity, since limiting components such as bearings or gears can be omitted. Most currently used actuation elements in continuum r...
Article
Full-text available
In minimally invasive surgery, new flexible instruments enable safer and easier access to difficult-to-reach anatomical regions. However, their introduction into the clinical workflow requires robust replanning, because navigation errors during surgery render initially planned trajectories infeasible. Such replanning requires to regularly solve an...

Zusammenfassung: Formgedächtnislegierungen (FGLen) werden bereits in verschiedensten Anwendungen in der Medizin eingesetzt. Hierzu zählen unter anderem medizinische Implantate, wie zum Beispiel Stents (Gefäßstützen) und orthodontische Drähte, die von der superelastischen Eigenschaft von Nickel-Titan Gebrauch machen. Darüber hinaus existiert jedoch...
Conference Paper
In this paper, the next generation of an SMA end-effector prototype is presented. The end-effector design is based on a modular concept. Each module has two degrees of freedom (DOFs) with independent SMA-bias-spring configurations. The first DOF, denoted as arm, can be positioned in plane within a 90 ° rotation radius. The second DOF, denoted as fi...
Conference Paper
A first prototype of an SMA-based reconfigurable end-effector was already presented at the SMA network exhibition booth at the Actuator14. In this paper, the next generation of the first SMA end-effector prototype is presented. The end-effector has four independent gripping arms, which can be positioned within a 90° rotation radius. The main part o...
