Tactile sensors with high spatial resolution are crucial to manufacture large scale flexible electronics, and low crosstalk sensor array combined with advanced data analysis is beneficial to improve detection accuracy. Here, we demonstrated the photo-reticulated strain localization films (prslPDMS) to prepare the ultralow crosstalk sensor array, which form a micro-cage structure to reduce the pixel deformation overflow by 90.3% compared to that of conventional flexible electronics. It is worth noting that prslPDMS acts as an adhesion layer and provide spacer for pressure sensing. Hence, the sensor achieves the sufficient pressure resolution to detect 1 g weight even in bending condition, and it could monitor human pulse under different states or analyze the grasping postures. Experiments show that the sensor array acquires clear pressure imaging and ultralow crosstalk (33.41 dB) without complicated data processing, indicating that it has a broad application prospect in precise tactile detection.

具有高空间分辨率的触觉传感器对于制造大规模柔性电子产品至关重要，低串扰传感器阵列结合先进的数据分析有利于提高检测精度。在这里，我们展示了用于制备超低串扰传感器阵列的光网状应变定位膜 (prslPDMS)，该阵列形成微笼结构，与传统柔性电子器件相比，像素变形溢出减少了 90.3%。值得注意的是，prslPDMS 充当粘附层并为压力传感提供垫片。因此，即使在弯曲条件下，传感器也能达到足够的压力分辨率来检测 1 g 重量，并且可以监测不同状态下的人体脉搏或分析抓握姿势。
