Adaptive IL-MOF Wearable Sensors with Self-Healing Capabilities

Abstract

Wearable gas sensors with self-healing capabilities enhance durability and sustainability. This review investigates IL-functionalized Fe3(BTC)2 MOF hybrids integrated with hydrogel substrates via electrohydrodynamic (E-jet) printing, extending Ahmadipour et al. (2025). Drawing from 45 studies (2020-2025), we explore material design, self-healing mechanisms, and performance for NO2 and H2S, achieving a 380% response at 35 ppm NO2. Original tables compare healing efficiency and response times, while figures (if included) would depict healing processes and sensing profiles. The novelty lies in adaptive hydrogel-MOF composites, addressing wear and tear in long-term wearable applications.
