Book Description
In Light Driven Micromachines, the fundamental principles and unique characteristics of light driven material structures, simple mechanisms and integrated machines are explored. Very small light driven systems provide a number of interesting features and unique design opportunities because streams of photons deliver energy into the system and provide the control signal used to regulate the response of the micron sized device. Through innovative material design and clever component fabrication, these optically powered tiny machines can be created to perform mechanical work when exposed to varying light intensity, wavelength, phase, and/or polarization. The book begins with the scientific background necessary to understand the nature of light and how light can initiate physical movement by inducing material deformation or altering the surrounding environment to impose micro-forces on the actuating mechanisms. The impact of physical size on the performance of light driven mechanisms and machines is discussed, and the nature of light–material interactions is reviewed. These interactions enable very small objects and mechanical components to be trapped and manipulated by a focused light beam, or produce local temperature gradients that force certain materials to undergo shape transformation. Advanced phase transition gels, polymers, carbon-based films and piezoelectric ceramics that exhibit direct light-to-mechanical energy conversion are examined from the perspective of designing optically driven actuators and mechanical systems. The ability of light to create photothermal effects that drive microfluidic processes and initiate the phase transformation of temperature sensitive shape memory materials are also explored in the book. This compendium seeks to inspire the next generation of scientists and engineers by presenting the fundamental principles of this emerging interdisciplinary technology and exploring how the properties of light can be exploited for microfluidic, microrobotic, biomedical and space applications.

Book Description
In Optical Nano and Micro Actuator Technology, leading engineers, material scientists, chemists, physicists, laser scientists, and manufacturing specialists offer an in-depth, wide-ranging look at the fundamental and unique characteristics of light-driven optical actuators. They discuss how light can initiate physical movement and control a variety of mechanisms that perform mechanical work at the micro- and nanoscale. The book begins with the scientific background necessary for understanding light-driven systems, discussing the nature of light and the interaction between light and NEMS/MEMS devices. It then covers innovative optical actuator technologies that have been developed for many applications. The book examines photoresponsive materials that enable the design of optically driven structures and mechanisms and describes specific light-driven technologies that permit the manipulation of micro- and nanoscale objects. It also explores applications in optofluidics, bioMEMS and biophotonics, medical device design, and micromachine control. Inspiring the next generation of scientists and engineers to advance light-driven technologies, this book gives readers a solid grounding in this emerging interdisciplinary area. It thoroughly explains the scientific language and fundamental principles, provides a holistic view of optical nano and micro actuator systems, and illustrates current and potential applications of light-driven systems.

Book Description
Micromachine technology and development is very recent in the long history of mechanical engineering. Yet as new microscopes make the miniature realms of micromechanisms accessible it is at this tiny scale that the biggest opportunities and challenges are to be found.Fujimasa, a leading Japanese researcher in this field, examines the brief history of the subject as well as the technologies that make micromachine fabrication possible. By examining the workings of life, and cells in particular, as good exemplars of micromachines, he is able to develop ideas fornew applications and working principles.There is, in Feynman's famous words about the limits of miniaturization, "Plenty of room at the bottom".

Book Description
Elastomeric optics exploit light transparent, variable translucent, and reflective stretchable polymers to create novel strain-tunable optical elements and flexible multifunctional optical sheets. Optical sheets are thin, large-area polymer light guide structures that can be used to create a wide variety of passive light harvesting and illumination systems. The book introduces the theoretical principles of elastomeric optics and explores how simple and complex mechanically deformable optical devices can be designed and fabricated. The transmission of light through these optical components or waveguides depends on the selected materials, surface interface, geometric design, optical coupling of embedded micro-structures, and degree of device deformation. In addition to providing a technical foundation for building adaptable optics, the book seeks to inspire the next generation of scientists and engineers to develop innovative solutions far beyond anything imagined today.
