Topic: Self-Healing Ionic Conductive Hydrogels for Flexible Pressure and Strain Sensors

Hydrogels hold promise as materials for soft actuators because of their qualities such as softness, transparency, and responsiveness to stimuli. This has led to their integration into the development of flexible pressure and strain sensors, addressing the escalating need for wearable devices in healthcare, robotics, and human-machine interfaces. However, weak and slow actuations remain challenging due to low modulus and osmosis-driven slow water diffusion, respectively. This Special Issue explores the potential of ionic conductive hydrogels in the context of flexible sensors, emphasizing their unique advantages and transformative impact on pressure and strain-sensitive devices. Examining the intricate interplay between material science and sensor engineering, we intend to uncover the promising applications, challenges, and future directions for these innovative hydrogel-based sensing technologies.
