(ΕΛΜΕΠΑ, Σχολή Μηχανικών (ΣΜΗΧ), ΔΠΜΣ Νανοτεχνολογία για Ενεργειακές Εφαρμογές, 2024-10-30) Papastefanakis, Dimitrios; Παπαστεφανάκης, Δημήτριος; Kymakis, Emmanouil; Κυμάκης, Εμμανουήλ
The Internet of Things (IoT) and wearable technology blend represents a transformative synergy in tech. This work kicks off by outlining IoT fundamentals and unique traits of wearables. A deep dive into IoT-enabled wearable hardware explores sensors, microcontrollers, connectivity, batteries, and interfaces. The focus shifts to strain sensors, detailing classifications (resistive, capacitive, optical), fabrication methods like 3D printing, and materials, mechanisms, and design considerations. Applications cross over healthcare, sports, gaming, robotics, and more. The experimental setup is presented in detail, featuring commercial sensors, electronic interfaces (op-amp, voltage divider), and data processing tools (Python, NumPy, Pandas, Matplotlib). Integration through Wi-Fi connection with IoT platforms like ThingSpeak and Blynk, using ESP8266, is explored. The conclusion highlights sensor output, online monitoring, analysis, and automation. It wraps up with conclusive remarks and future research avenues.
