Computer Architectures for Smart Sensors in Body Area Networks (Arquitecturas de computadores para sensores inteligentes en redes de área del cuerpo).

GreenPatch aims to advance sustainable smart sensor technologies for human well-being, extending beyond medical applications to include general lifestyle monitoring. The project focuses on the development of environmentally friendly, disposable, multisensor wearable devices based on biodegradable substrates and functional inks.
The project explores two complementary wearable technologies: a disposable smart patch incorporating sensors and low-resource processing capabilities, and a garment-integrated Body Area Network (BAN). The smart patch uses a custom inductive radio-frequency (RF) link for wireless power and data transmission, eliminating the need for batteries. The system combines flexible integrated circuits with sustainable materials, with the long-term goal of moving towards biodegradable MOS technology.
The project also investigates energy-efficient digital circuits and computer architectures based on the 32-bit RISC-V ecosystem. Particular attention is given to resource-constrained embedded systems, Tiny Machine Learning (TinyML), multisensor data acquisition and processing, and the verification and integration of flexible electronic systems.
Ultimately, GreenPatch seeks to contribute to the development of low-cost, versatile and sustainable wearable technologies, supporting the transition towards environmentally responsible electronics and contributing to the European Union’s circular economy objectives.
