Artificial sense technologies predominantly rely on visual and tactile input, which often prove inadequate in obscured or opaque environments. Inspired by the natural electrosensory capabilities of electrogenic fishes, we introduce an organic electrosense transistor designed to detect electric fields generated by nearby objects, facilitating the creation of impalpable perception systems. Unlike traditional sensors, our electrosense transistor perceives bipolar electric fields with high sensitivity and stability. We use compact models and device simulations to elucidate the mechanisms of charge induction and transport within organic electrosense transistors when exposed to spatial electric fields. Demonstrating its practical utility, we show that robots equipped with our electrosense transistor can successfully navigate and detect concealed objects without requiring direct contact. This work not only advances the understanding of charge dynamics in electrosensory systems but also establishes a platform for developing highly sensitive, noninvasive artificial sensing technologies applicable in surveillance, search and rescue, and other challenging environments.
人工传感技术主要依赖视觉和触觉输入，而在遮挡或不透明环境中，这些输入往往显得不足。受发电鱼类自然电感应能力的启发，我们推出了一种有机电感应晶体管，旨在检测附近物体产生的电场，有助于创建无形感知系统。与传统传感器不同，我们的电感应晶体管能够以高灵敏度和稳定性感知双极电场。我们使用紧凑模型和器件模拟来阐明有机电感应晶体管在暴露于空间电场时电荷感应和传输的机制。为证明其实际效用，我们展示了配备我们的电感应晶体管的机器人能够成功导航并检测隐藏物体，而无需直接接触。这项工作不仅增进了我们对电感应系统中电荷动力学的理解，还建立了一个平台，用于开发适用于监视、搜索和救援以及其他具有挑战性环境的高灵敏度、非侵入式人工传感技术。
