sensorarrays are essential for effective human-machine interaction (HMI), enabling systems to perceive, interpret, and respond to human actions. However, traditional sensorarrays 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 singlechannel, enhancing efficiency and simplicity. The versatility of these sensorarrays 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.
