Real‐time detection and differentiation of diverse external stimuli with one tactile senor remains a huge challenge and largely restricts the development of electronic skins. Although different sensors have been described based on piezoresistivity, capacitance, and triboelectricity, and these devices are promising for tactile systems, there are few, if any, piezoelectric sensors to be able to distinguish diverse stimuli in real time. Here, a human skin‐inspired piezoelectric tactile sensor array constructed with a multilayer structure and row+column electrodes is reported. Integrated with a signal processor and a logical algorithm, the tactile sensor array achieves to sense and distinguish the magnitude, positions, and modes of diverse external stimuli, including gentle slipping, touching, and bending, in real time. Besides, the unique design overcomes the crosstalk issues existing in other sensors. Pressure sensing and bending sensing tests show that the proposed tactile sensor array possesses the characteristics of high sensitivity (7.7 mV kPa⁻¹), long‐term durability (80 000 cycles), and rapid response time (10 ms) (less than human skin). The tactile sensor array also shows a superior scalability and ease of massive fabrication. Its ability of real‐time detection and differentiation of diverse stimuli for health monitoring, detection of animal movements, and robots is demonstrated.

具有无串扰行+列电极的皮肤启发压电触觉传感器阵列，用于时空区分不同的刺激

用一个触觉传感器实时检测和区分不同的外部刺激仍然是一个巨大的挑战，并在很大程度上限制了电子皮肤的发展。尽管基于压阻、电容和摩擦电描述了不同的传感器，并且这些设备对于触觉系统很有前景，但很少有压电传感器能够实时区分不同的刺激。在这里，报道了一种由多层结构和行+列电极构成的受人体皮肤启发的压电触觉传感器阵列。触觉传感器阵列与信号处理器和逻辑算法集成，实现实时感知和区分各种外部刺激的大小、位置和模式，包括轻微的滑动、触摸和弯曲。此外，独特的设计克服了其他传感器存在的串扰问题。^{压力传感和弯曲传感测试表明，所提出的触觉传感器阵列具有高灵敏度（7.7 mV kPa -1}）、长期耐用（80 000次循环）和快速响应时间（10 ms）（小于人体皮肤）的特点。）。触觉传感器阵列还表现出卓越的可扩展性和易于大规模制造的特点。展示了其实时检测和区分各种刺激的能力，用于健康监测、动物运动检测和机器人。
