N2  - Electrical impedance tomography (EIT) is a technique employed in tactile sensing to create an image of impedance changes within a continuous sensor using electrodes placed only at the perimeter. This is advantageous for soft sensing 'e-skins' being developed for applications such as robotics and human-machine interactions. EIT was originally developed for medical diagnostics and has more recently been adopted for tactile imaging, which has distinct requirements and challenges. This book explains the fundamentals of EIT at a basic level, without requiring a high level of mathematical expertise, making it an accessible text for students and newcomers to the field. It also covers applications and challenges of the method, recent developments, and practical implications. Part of IOP Series in Sensors and Sensor Systems
