Invited: IoB: The Vision of the Internet of Bodies

Over six decades of semiconductor technology scaling (Moore's Law) and subsequently system size scaling (Bell's Law) has reduced the size of unit computing to virtually zero. This has led to computing becoming ubiquitous in everything around us, making everyday things smart. Similarly, tremendous progress in communication capacity (Shannon's theorem) has made these smart things connected to the internet and forming the Internet of Things (IoT). Many of these smart, connected devices are present in, on, or around the human body. This subset of IoT around the human body has a distinguishing feature, that it has a common medium, i.e. the body itself. This subset is increasingly becoming popular as the Internet of Bodies (IoB). In this paper, we look into the need and growth of IoB devices, including the technological landscape, current challenges and the future that IoB will enable for empowering humans.
