Special Issue Information

Dear Colleagues,

The rapid evolution of flexible pressure/force sensors has revolutionized sensing technologies, enabling their seamless integration into dynamic environments. These sensors, characterized by their deformability, lightweight nature, and high sensitivity, have emerged as pivotal tools in advancing fields such as healthcare, robotics, consumer electronics, and industrial automation. Recent breakthroughs in materials science have enhanced their performance, durability, and adaptability. This Special Issue highlights cutting-edge research on flexible sensor design, fabrication techniques, and real-world applications. It explores how these sensors contribute to innovative solutions, from wearable health monitors and tactile sensors in robotics to smart infrastructure and precision control in manufacturing.

Flexible magnetic tactile sensors hold transformative potential in robotics and human–computer interactions by enabling precise force detection. However, existing sensors face challenges in balancing sensitivity, detection range, and structural adaptability for sensing force. This study proposed a pre-compressed magnetization method to address these limitations by amplifying the magnetoelastic effect through optimized magnetization direction distribution of the elastomer. A body-centered cubic lattice-structured magnetoelastomer featuring regular deformation under compression was fabricated via digital light processing (DLP) to validate this method. Finite element simulations and experimental analyses revealed that magnetizing the material under 60% compression strain optimized magnetization direction distribution, enhancing force–magnetic coupling. Integrating the magnetic elastomer with a hall sensor, the prepared tactile sensor demonstrated a low detection limit (1 mN), wide detection range (0.001–10 N), rapid response/recovery times (40 ms/50 ms), and durability (>1500 cycles). By using machine learning, the sensor enabled accurate 3D force prediction. Full article
