Multi‐Mode Flexible Tactile Sensor Based on Bionic Strategy for Pressure and Position Detection

Abstract Flexible tactile sensors are an essential medium for human‐machine interactions (HMI). However, traditional flexible tactile sensors lead to challenges such as structural redundancy and complex data processing. This paper presents a biomimetic multi‐mode flexible tactile sensor (B‐MTS) based on biomimetic strategies. This B‐MTS consists of a pressure‐sensing layer and a positioning layer. The B‐MTS exhibits high sensitivity (484.6 kPa −1 ) owing to the bionic crack structures. The positioning layer utilizes the alternating current (AC) signal generated by the coupling of the power‐frequency electric and magnetic fields with the human body as a signal source. With only two interfaces, it can achieve rapid identification of the touch position (<10 ms). Thanks to its ability to sense both pressure and position simultaneously (≤250 Pa), B‐MTS is successfully integrated into encrypted cryptographic devices, ensuring robust privacy protection. Additionally, B‐MTS is applied in piano performance and UAV control, opening new possibilities for the development of secure identification and intelligent interaction technologies.
