Artificial electronic skins (e-skins) comprise an integrated matrix of flexible devices arranged on a soft, reconfigurable surface. These sensors must perceive physical interaction spaces between external objects and robots or humans. Among various types of sensors, flexible magnetic sensors and the matrix configuration are preferable for such position sensing. However, sensor matrices must efficiently map the magnetic field with real-time encoding of the positions and motions of magnetic objects. This paper reports an ultrathin magnetic sensor matrix system comprising a 2 × 4 array of magnetoresistance sensors, a bootstrap organic shift register driving the sensor matrix, and organic signal amplifiers integrated within a single imperceptible platform. The system demonstrates high magnetic sensitivity owing to the use of organic amplifiers. Moreover, the shift register enabled real-time mapping of 2D magnetic field distribution.

集成了有机驱动器和放大器电路的不易察觉的磁传感器矩阵系统。

人造电子皮肤（e皮肤）包括布置在柔软，可重新配置的表面上的柔性设备的集成矩阵。这些传感器必须感知外部物体与机器人或人类之间的物理交互空间。在各种类型的传感器中，柔性磁性传感器和矩阵配置对于这种位置感测是优选的。但是，传感器矩阵必须通过对磁性物体的位置和运动进行实时编码来有效地映射磁场。本文报道了一种超薄型磁传感器矩阵系统，该系统包括一个2×4阵列的磁阻传感器，一个驱动该传感器矩阵的自举有机移位寄存器以及集成在单个感知平台内的有机信号放大器。由于使用了有机放大器，该系统显示出很高的磁灵敏度。
