Dynamic Bio-Ink Tattoos for Adaptive Health Monitoring and Precision Drug Delivery

Abstract

We propose a biocompatible tattoo system that merges nanosensing , microfluidics, and wireless communication into a single skin-adherent platform. Unlike existing wearables, this design uses AI-driven reconfiguration to prioritize biomarkers dynamically, self-healing materials to maintain function under stress, and bidirectional microfluidics for active sampling and drug delivery. The system supports real-time health tracking, localized therapy, and covert data transmission, with applications in chronic disease management, defense, and biometric security.
