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. 1.

She received a BS in physics from MIT and a PhD in electrical engineering from the University of Pennsylvania. Dr Smela then worked as a research scientist in Link�oping, Sweden and in Ris�, Denmark before becoming Vice President of Research and Development at Santa Fe Science and Technology, NM. Dr Smela's research interests have focused on polymeric and cell-based sensors and actuators. She has served as Associate Dean for Faculty and Graduate Affairs, Equity Administrator, and Diversity Officer at the University of Maryland. She spent a year as a Jefferson Science Fellow at the Department of State to stand up the US-ASEAN Smart Cities Network. She has recently been working with a group of engineering faculty to better integrate sustainability concepts throughout the undergraduate curriculum.
