This text shows how to design and fabricate optical microsystems using innovative technologies and and original architectures. A barcode scanner, laser projection mirror and a microspectrometer are explained in detail, starting from the system conception, discussing simulations, choice of cleanroom technologies, design, fabrication, device test, packaging all the way to the system assembly. An advanced microscanning device capable of one- and two-dimensional scanning can be integrated in a compact barcode scanning system composed of a laser diode and adapted optics. The original design of the microscanner combines efficiently the miniaturized thermal mechanical actuator and the reflecting mirror, providing a one-dimensional scanning or a unique combination of two movements, depending on the geometry. The simplicity of the device makes it a competitive component. The authors rethink the design of a miniaturized optical device and find a compact solution for a microspectrometer, based on a tunable filter and a single pixel detector. A porous silicon technology combines efficiently the optical filter function with a thermal mechanical actuator on chip.The methodology for design and process calibration are discussed in detail. The device is the core component of an infrared gas spectrometer.

The use of neural implants for stimulation and recording show excellent promise in restoring certain functions to the central nervous system; and neuroprostheses remains one of the most important tools of neuroscientists for the elucidation of the brain's function. 　Ailments such as Parkinson's disease, obesity, blindness, and epilepsy are being studied from this angle. Development of better electrodes for recording and stimulation is therefore critical to ensure continuing progress in this field.This book addresses one of the main clinical complications with the use of electrodes, namely the reaction of the neurological tissue in the immediate vicinity of an implanted device. The authors describe new techniques for assessing this phenomenon, as well as new microfabrication techniques to impede the inflammatory response of the brain. Inflammation can adversely effect these devices, limiting their lifetime and reducing their effectiveness. The measurement protocols and improved fabrication protocols described within these pages will become standard tools in the future of neuroprostheses. 　　The author holds two U.S. patents on microassembly and is also a Review Editor for Frontiers in Neuroengineering.
