Abstract:The synergistic enhancement of both linear range and response speed is crucial for simplifying the signal processing/conversion of tactile sensors and improving real-time perception. However, traditional tactile sensors face challenges in quantitatively controlling force-electrical response and viscoelastic hysteresis, limiting their linear sensing range and response speed. Inspired by parallel structures, Composite Parallel Tactile Sensors (CPTS-W and CPTS-S) is proposed, employing parallel elastomers to regulate deformation precisely. These sensors exhibit a wide sensing range up to 450 kPa, with three linear response regions: 0–50 kPa (sensitivity of 0.0080 kPa−¹), 50–98 kPa (sensitivity of 0.0022 kPa−¹), and 98–423 kPa (sensitivity of 0.0012 kPa−¹), significantly reduce dynamic recovery hysteresis of conductive composites, and enhance rapid response capability (48 ms response time and 39 ms recovery time). With excellent dynamic response characteristics across a wide linear sensing range, the results demonstrate broad applicability in areas such as physiological signal monitoring, complex object shape recognition, and multi-axis torque decoupling perception in robotics.
