Smart Skins and Intelligent Signals AI-Augmented Body Channel Communication for Next-Gen Wearables

Abstract

Flexible electronics with stretchable substrates have brought a revolutionary change to wearable technology because they merge effortlessly into human skin. The systems use advanced sensors along with amplifiers and microcontrollers, and power management modules to monitor vital signs nonstop while still providing a comfortable user experience. Body Channel Communication (BCC) represents a crucial element for this innovation because it employs human bodies to safely transmit data at low power usage and maintains excellent signal quality while protecting sensitive information much better than regular wireless methods. The real-world utilization of BCC presents multiple implementation barriers due to differences in body channel models, backward signal loss and changing contact impedance and strict spectral mask limitations and crystalless design constraints, and specific antenna characteristics of human bodies. The research investigates Body- Centric Communication (BCC) functions in wearable flexible electronics through the examination of its advantages and resolution of primary design challenges, as well as recent technological advancements from RedTacton-inspired innovations. The study addresses key barriers to make BCC operate at its maximum potential in creating efficient, flexible wearable devices for upcoming applications.
