Book Description

This book covers state-of-the-art development in microfluidics-enabled soft manufacturing (MESM), ranging from fundamentals to applications. The book addresses the long-standing challenge in the manufacture of simultaneously achieving both precise control over nano-/micro-scale structures and large-scale fabrication of materials for pragmatic use, with microfluidics-enabled soft manufacture to fill the gap between the widely-varied length scales involved. It offers a comprehensive insight into the microfluidic generation of fluid systems as liquid templates, such as droplets, bubbles, jets, emulsions, and foams, which are categorized into individual templates, one-dimensional arrays, and two-/three-dimensional assemblies for the modular fabrication of microparticles, microfibers, and porous materials, respectively. MESM enriches the compositional and structural diversity of engineered materials for well-tailored properties and functionalities, markedly broadening the application horizons across interdisciplinary fields, including engineering, environment, physics, chemistry, biology, and medicine. This book aims to systematize this emerging yet versatile and powerful technology, with the hope of aiding the realization of its full potential. Microfluidics-Enabled Soft Manufacture will be an invaluable reference for graduate students, postgraduates, researchers, and practitioners/professionals working in micro and nanofabrication, materials science, surface science, fluid dynamics, and engineering.

Book Description

Soft and Stiffness-controllable Robotics Solutions for Minimally Invasive Surgery presents the results of a research project, funded by European Commission, STIFF-FLOP: STIFFness controllable Flexible and Learn-able manipulator for surgical Operations. In Minimally Invasive Surgery (MIS), tools go through narrow openings and manipulate soft organs that can move, deform, or change stiffness. There are limitations on modern laparoscopic and robot-assisted surgical systems due to restricted access through Trocar ports, lack of haptic feedback, and difficulties with rigid robot tools operating inside a confined space filled with organs. Also, many control algorithms suffer from stability problems in the presence of unexpected conditions. Yet biological "manipulators", like the octopus arm can manipulate objects while controlling the stiffness of selected body parts and being inherently compliant when interacting with objects. STIFF-FLOP robot is an innovative soft robotic arm that can squeeze through a standard MIS, reconfigure itself and stiffen by hydrostatic actuation to perform compliant force control tasks while facing unexpected situations. Technical topics discussed in the book include:Soft actuatorsContinuum soft manipulatorsControl, kinematics and navigation of continuum manipulatorsOptical sensors for force, torque, and curvatureHaptic feedback and human interface for surgical systemsValidation of soft stiffness controllable robots
