Abstract

The development of bionic sensing devices with advanced physiological functionalities has attracted significant attention in flexible electronics. In this study, we innovatively develop an air-stable photo-induced n-type dopant and a sophisticated photo-induced patterning technology to construct high-resolution joint-free p-n integrated thermoelectric devices. The exceptional stability of the photo-induced n-type dopant, combined with our meticulously engineered joint-free device architecture, results in extremely low temporal and spatial variations. These minimized variations, coupled with superior linearity, position our devices as viable candidates for artificial thermoreceptors capable of sensing external thermal noxious stimuli. By integrating them into a robotic arm with a pain perception system, we demonstrate accurate pain responses to external thermal stimuli. The system accurately discerns pain levels and initiates appropriate protective actions across varying intensities. Our findings present a novel strategy for constructing high-resolution thermoelectric sensing devices toward precise biomimetic thermoreceptors.

高可靠性热电感受器与最小的时间和空间变化通过光诱导模式热电。

具有先进生理功能的仿生传感装置的开发已成为柔性电子领域的研究热点。在这项研究中，我们创新地开发了一种空气稳定的光诱导n型掺杂剂和一种复杂的光诱导图像化技术，以构建高分辨率的无关节p-n集成热电器件。光致n型掺杂剂的卓越稳定性，结合我们精心设计的无关节器件结构，导致极低的时间和空间变化。这些最小的变化，加上优越的线性，使我们的设备成为能够感知外部热有害刺激的人工热感受器的可行候选者。通过将它们集成到具有疼痛感知系统的机械臂中，我们展示了对外部热刺激的准确疼痛反应。该系统能准确识别疼痛程度，并在不同强度下启动适当的保护措施。我们的研究结果为构建高精度仿生热感受器的高分辨率热电传感装置提供了一种新的策略。

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
