This book presents some basic flexure geometries and the analytic models, which can be assessed for specific design applications. The author then goes beyond this fundamental explanation to explore more sophisticated issues. Specifically, the text discusses integration of these flexure geometries and analytic models to produce useful mechanisms for precise motion control with fast dynamic response. This book will be useful for advanced undergraduate and graduate students, particularly those who hope to acquire competence in experimental and mechanical sciences. Practicing engineers and other scientists currently working in related fields will also benefit from Flexure.
