The shape – morphing performance of magnetoactive soft materials

Magnetoactive soft materials (MSMs) are soft polymeric composites filled with magnetic particles that are an emerging class of smart and multifunctional materials with immense potentials to be used in various applications including but not limited to artificial muscles, soft robotics, controlled drug delivery, minimally invasive surgery, and metamaterials. Advantages of MSMs include remote contactless actuation with multiple actuation modes, high actuation strain and strain rate, self-sensing, and fast response etc. Having broad functional behaviours offered by the magnetic fillers embedded within non-magnetic matrices, MSMs are undoubtedly one of the most promising materials in applications where shape-morphing, dynamic locomotion, and reconfigurable structures are highly required. This review article provides a comprehensive picture of the MSMs focusing on the materials, manufacturing processes, programming and actuation techniques, behaviours, experimental characterisations, and device-related achievements with the current state-of-the-art and discusses future perspectives. Overall, this article not only provides a comprehensive overview of MSMs’ research and development but also functions as a systematic guideline towards the development of multifunctional, shape-morphing, and sophisticated magnetoactive devices

System and method for operating a follower vehicle in a vehicle platoon

Patent no. US9927816B2A method for operating a follower vehicle in a vehicle platoon includes determining, during operation, whether the follower vehicle is operating in a normal state or an abnormal state based on an operation condition of a component of the follower vehicle, or a communication between the follower vehicle and a preceding vehicle in the vehicle platoon. The method further includes selecting a first control mode if the follower vehicle is in the normal state and a second control mode if the follower vehicle is in the abnormal state so as to control movement of the follower vehicle using the selected control mode. In the first control mode, the follower vehicle uses communication data received from the preceding vehicle in the vehicle platoon to control its movement. In the second control mode, the follower vehicle uses data obtained by one or more of its sensors to control its movement.info:eu-repo/semantics/publishedVersio

Optimization and application of a flexible dual arm robot based automation system for sample preparation and measurement

This dissertation describes the optimization of the implementation of the Yaskawa SDA10F dual-arm robot to carry out routine sample preparation tasks in a life science laboratory such that standard lab equipment can be used and the robot can replace humans in sample preparation process. The existing robot control software is changed to carry out various tasks consecutively without interruption. Robot environment and motions were optimized allowing system expansion, multiple batches of samples are made at a time, increasing throughput. The system was validated with the help of two applications

Soft liver phantom with a hollow biliary system

Einleitung: Die flexible Endoskopie bietet eine ständig wachsende Zahl innovativer diagnostischer und therapeutischer Möglichkeiten bei hepatobiliären Erkrankungen. Diese fortschrittlichen Verfahren, die mitunter komplex und gar nicht so selten mit relevanten Komplikationen verbunden sind, erfordern spezielle technische Fertigkeiten, ein profundes anatomisches Wissen und eine lange Lernkurve, die praktisch trainiert werden muss. Für ein patientenunabhängiges Training endoskopischer und endosonographischer Eingriffe sollte ein weiches, naturgetreues und langlebiges Leberorganmodell mit detaillierter Morphologie zur Verfügung stehen. In dieser Arbeit wird ein praktikables und kostengünstiges selbst hergestelltes weiches Lebermodell mit anatomisch korrektem Gallensystem vorgestellt. Methode: Mit Hilfe von 3D-Druck- und Weichstoffformungstechnologien wurde ein nahezu realistisches Lebermodell mit einem komplexen, hohlen Gallensystem hergestellt. Die Anatomie des Lebermodells wurde mittels Computertomographie (CT), Ultraschall und Endoskopie validiert. Nach Aufbereitung und Auswertung der Bildgebung wurden interventionelle transhepatische Eingriffe eingeleitet. Zur Validierung der Trainingseffekte und der individuellen Kompetenz wurde ein genaues Bewertungssystem für den transhepatischen Zugang etabliert. Ergebnisse: Ein realistisches Lebermodell wurde erfolgreich entwickelt und hergestellt. Die CT-Ergebnisse zeigen, dass das Lebermodell die detaillierte Anatomie wiedergibt, mit einem räumlichen Root Mean Square Error (RMSE) von 0,9 ± 0,2 mm und 1,7 ± 0,7 mm für die äußere Form bzw. den Gallengang. Das endosonographische Bild des Modells ist realistisch und die Dimension der Gallengänge ist konsistent. Die transhepatische Punktion der Gallengänge war durchführbar und ein elektronisches Abtastsystem zur quantitativen Lokalisierung der transhepatischen Nadel in Echtzeit war erfolgreich möglich. Schlussfolgerung: Das vorgestellte künstliche Lebermodell für das endoskopische und endosonografische Training kommt der Realität einer normalen Leber sehr nahe, ist kostengünstig, einfach zu reproduzieren und für die Serienproduktion geeignet. Mit dem elektronischen Sensormodul lässt sich der Trainingserfolg objektiv kontrollieren. Neben der transhepatischen Punktion könnten an diesem Modell weitere Eingriffe trainiert werden, wie z. B. endoskpischen retrograden Cholangiopankreatographie (ERCP), perkutane transhepatische Cholangiographie oder choliangiographische Drainage (PTC/PTCD), perkutane holedochofiberoskopie (POC), endoskopische ultraschallgeführte biliäre Drainage (EUS-BD)
