The development of pressure sensor arrays capable of distinguishing the shape and texture details of objects is of considerable interest in the emerging fields of smart robots, prostheses, human-machine interfaces, and artificial intelligence (AI). Here we report an integrated pressure sensor array, by combining solution-processed two-dimensional (2D) MoS₂ van der Waals (vdW) thin film transistor (TFT) active matrix and conductive micropyramidal pressure-sensitive rubber (PSR) electrodes made of polydimethylsiloxane/carbon nanotube composites, to achieve spatially revolved pressure mapping with excellent contrast and low power consumption. We demonstrate a 10 × 10 active matrix by using the 2D MoS₂ vdW-TFTs with high on-off ratio > 10⁶, minimal hysteresis, and excellent device-to-device uniformity. The combination of the vdW-TFT active matrix with the highly uniform micropyramidal PSR electrodes creates an integrated pressure sensing array for spatially resolved pressure mapping. This study demonstrates that the solution-processed 2D vdW-TFTs offer a solution for active-matrix control of pressure sensor arrays, and could be extended for other active-matrix arrays of electronic or optoelectronic devices.

能够区分物体形状和纹理细节的压力传感器阵列的开发在智能机器人、假肢、人机界面和人工智能 (AI) 等新兴领域引起了极大的兴趣。在这里，我们通过将溶液处理的二维 (2D) MoS ₂范德华 (vdW) 薄膜晶体管 (TFT) 有源矩阵和由聚二甲基硅氧烷制成的导电微锥压敏橡胶 (PSR) 电极相结合，报告了一种集成压力传感器阵列/碳纳米管复合材料，以实现具有出色对比度和低功耗的空间旋转压力映射。我们通过使用具有高开关比 > 10 ⁶的 2D MoS ₂ vdW-TFT展示了 10 × 10 有源矩阵、最小滞后和出色的器件间一致性。vdW-TFT 有源矩阵与高度均匀的微锥体 PSR 电极的组合创建了一个用于空间分辨压力映射的集成压力传感阵列。这项研究表明，解决方案处理的 2D vdW-TFT 为压力传感器阵列的有源矩阵控制提供了解决方案，并且可以扩展到电子或光电设备的其他有源矩阵阵列。
