Sensor arrays are essential for effective human‐machine interaction (HMI), enabling systems to perceive, interpret, and respond to human actions. However, traditional sensor arrays often involve complex manufacturing processes and excessive wiring due to point‐to‐point connections. To address these challenges, a type of self‐powered, low‐cost sensor array is described that minimizes these issues. Utilizing the principles of contact electrification and electrostatic induction, the array consists of two or more interconnected electrostatic induction units. When a unit is triggered, it generates a unique voltage signal relative to other connected units, resulting in diverse signals with specific waveforms and peak magnitudes. This diversity allows the sensor array to output multiple addressable signals through a limited number of channels or a single channel, enhancing efficiency and simplicity. The versatility of these sensor arrays in various HMI applications is demonstrated, including game joysticks, electronic skins, robot controllers, and leaf‐based electronic piano keyboards, showcasing their potential to transform HMI technology.

自供电、基于原材料的传感器阵列，具有最小的信号通道，用于人机交互


传感器阵列对于有效的人机交互 （HMI） 至关重要，使系统能够感知、解释和响应人类操作。然而，由于点对点连接，传统的传感器阵列通常涉及复杂的制造过程和过多的布线。为了应对这些挑战，本文描述了一种自供电、低成本的传感器阵列，可以最大限度地减少这些问题。利用触点通电和静电感应原理，该阵列由两个或多个互连的静电感应单元组成。当一个单元被触发时，它会生成相对于其他连接单元的独特电压信号，从而产生具有特定波形和峰值幅度的不同信号。这种分集性使传感器阵列能够通过有限数量的通道或单个通道输出多个可寻址信号，从而提高效率和简单性。展示了这些传感器阵列在各种 HMI 应用中的多功能性，包括游戏操纵杆、电子皮肤、机器人控制器和基于树叶的电子钢琴键盘，展示了它们改变 HMI 技术的潜力。
