The book “Case Studies in Micromechatronics – From Systems to Process” offers prominent sample applications of micromechatronic systems and the enabling fabrication technologies. The chosen examples represent five main fields of application: consumer electronics (pressure sensor), mobility and navigation (acceleration sensor), handling technology and automation (micro gripper), laboratory diagnostics (point of care system), and biomedical technology (smart skin). These five sample systems are made from different materials requiring a large variety of modern fabrication methods and design rules, which are explained in detail. As a result, an inverted introduction “from prominent applications to base technologies” is provided. Examples of applications are selected to offer a broad overview of the development environment of micromechatronic systems including established as well as cutting-edge microfabrication technologies.
