Special Issue Information

Dear Colleagues,

Flexible sensing electronics play a crucial role as the primary mediums through which high-end equipment perceives external information. Today, flexible sensing devices based on various functional sensing materials or innovative structural designs provide broad potential applications in human–machine interaction, smart healthcare, and advanced mechanical systems. However, current sensing materials and structures still require further improvements to meet the increasing demands of real-world applications, including enhanced sensitivity, durability, and multifunctionality. This Special Issue aims to present the latest research advancements in advanced sensing materials and structures for applications in wearable electronics, robotic skin, intelligent machinery, and beyond. Topics of interest include but are not limited to, novel material design, flexible and stretchable sensors, self-powered sensing technologies, and integrated multifunctional sensor systems. We invite researchers to submit original research to this Special Issue.

Flexible sensors have emerged as essential components in next-generation technologies such as wearable electronics, smart healthcare, soft robotics, and human–machine interfaces, owing to their outstanding mechanical flexibility and multifunctional sensing capabilities. Despite significant advancements, challenges such as the trade-off between sensitivity and detection range, and poor signal stability under cyclic deformation remain unresolved. To overcome the aforementioned limitations, this work introduces a high-performance soft sensor featuring a dual-layered electrode system, comprising silver nanoparticles (AgNPs) and a composite of multi-walled carbon nanotubes (MWCNTs) with carbon black (CB), coupled with a laser-engraved crack-gradient microstructure. This structural strategy facilitates progressive crack formation under applied strain, thereby achieving enhanced sensitivity (1.56 kPa−1), broad operational bandwidth (50–600 Hz), fine frequency resolution (0.5 Hz), and a rapid signal response. The synergistic structure also improves signal repeatability, durability, and noise immunity. The sensor demonstrates strong applicability in health monitoring, motion tracking, and intelligent interfaces, offering a promising pathway for reliable, multifunctional sensing in wearable health monitoring, motion tracking, and soft robotic systems.
