Jose Gerardo Vieira da Rocha ´ received the BSc, MSc, and PhD degrees from the University of Minho, Guimaraes, Portugal, in 1995, 1999 and 2004, respectively, all in industrial electronics engineering. A significant part of his PhD work was done at Delft University of Technology, Delft, The Netherlands. Since 2004, he has been an assistant professor with the Department of Industrial Electronics, University of Minho, where he is involved in the research of radiation sensors.
This book describes some devices that are commonly identified as tactile or force sensors. This is achieved with different degrees of detail, in a unique and actual resource, through the description of different approaches to this type of sensors. Understanding the design and the working principles of the sensors described here requires a multidisciplinary background of electrical engineering, mechanical engineering, physics, biology, etc. An attempt has been made to place side by side the most pertinent information in order to reach a more productive reading not only for professionals dedicated to the design of tactile sensors, but also for all other sensor users, as for example, in the field of robotics. The latest technologies presented in this book are more focused on information readout and processing: as new materials, micro and sub-micro sensors are available, wireless transmission and processing of the sensorial information, as well as some innovative methodologies for obtaining and interpreting tactile information are also strongly evolving.
