Abstract:

We are living in the age of human-machine augmentation and coexistence (e.g., smartphones, AI assistants, computers, earbuds, smart watches) and steadily marching towards a new age of human-machine seamless cooperation (HMC) or even symbiosis. Radiative communication using electromagnetic (EM) fields is the state-of-the-art for connecting wearable and implantable devices enabling prime applications in the fields of connected healthcare, electroceuticals, neuroscience, augmented and virtual reality (AR/VR) and human-computer interaction (HCI) and HMC, forming a subset of the Internet of Things called the Internet of Bodies (IoB). However, owing to such radiative nature of the traditional wireless communication, EM signals propagate in all directions, inadvertently allowing an eavesdropper to intercept the information. Moreover, since only a fraction of the energy is picked up by the intended device, and the need for high carrier frequency compared to information content, wireless communication tends to suffer from poor energy-efficiency (>nJ/bit). Noting that all IoB devices share a common medium, i.e. the human body, utilizing the conductivity of the human the body allows low-loss transmission, termed as human body communication (HBC) and improves energy-efficiency. Conventional HBC implementations still suffer from significant radiation compromising physical security and efficiency. Our recent work has developed Electro-Quasistatic Human Body Communication (EQS-HBC), a method for localizing signals within the body using low-frequency transmission, thereby making it extremely difficult for a nearby eavesdropper to intercept critical private data, thus producing a covert communication channel, i.e., the human body as a ‘wire’ along with reducing interference and providing 100x more efficient communication than Bluetooth.

In this talk, I will highlight recent advancements in the field of IoB enabled by the Body-as-a-Wire technology which has a strong promise to become the future of Body Area Network (BAN) along with it’s counterpart in the Brain leading to broadband communication. We will focus on the circuit model developed in recent literature explaining the fundamental behavior of Electro-Quasistatic Body and Brain Communication, leading to understanding of channel loss. We will finally show how such low-power communication is paving the way forward for Secure and Efficient IoB for seamless Human-Machine Co-operation.
