Discussion

This study demonstrates enhanced humidity resistance and multifunctional sensing in eutectogels, indicating their potential in flexible sensors.

A eutectogel developed with hydrophobic deep eutectic solvents shows remarkable humidity resistance, absorbing only 2.8% water over 30 days.
Sensors made from this gel retain 99.3% of their toughness even after a year in humid conditions, showcasing excellent mechanical properties.
Radical copolymerization of acrylic acid monomers was used to create the gel, which excels in real-time monitoring of strain, pressure, and temperature.
This work supports the development of durable, multifunctional gels for applications in flexible electronic sensors, enhancing their usability.
