Abstract

Highlights

A novel organohydrogel-based multimodal e-skin with excellent sensing performance for temperature, humidity, pressure, proximity, and NO₂ is proposed for the first time, showing powerful sensing capabilities beyond natural skin.
The developed multimodal e-skin exhibited extraordinary sensing performance at room temperature, including fast pressure response time (0.2 s), high temperature sensitivity (9.38% °C^-1), a wide range of humidity response (22%–98% RH), high NO₂ sensitivity (254% ppm^-1), a low detection limit (11.1 ppb NO₂) and the abilities to sense the proximity of objects accurately, which are yet achieved by previous e-skins.
The multimodal e-skin was combined with the deep neural network algorithm and wireless alarm circuit to achieve zero-error classification of different objects and rapid response to NO_x leak incidents, proving the feasibility of the e-skin-assisted rescue robot for post-earthquake rescue.

设计用于环境物体识别和无线有毒气体报警的人工智能增强型和硬件支持的多模态电子皮肤。

由于废墟结构不稳定和余震不断，震后救援任务充满挑战。目前的救援机器人大多缺乏与环境互动的能力，导致救援效率低下。此次提出的多模态电子皮肤（e-skin）不仅再现了自然皮肤的压力、温度和湿度感知能力，还开发了自然皮肤之外的感知功能--感知物体的接近程度和二氧化氮气体。基于 Ecoflex 和有机水凝胶的多层堆叠结构使电子皮肤具有与天然皮肤相似的机械性能。集成了多模态电子皮肤和人工智能（AI）算法的救援机器人具有很强的环境感知能力，能准确分辨物体并通过抓取识别人体肢体，为震后自动救援奠定了基础。此外，电子皮肤与二氧化氮无线报警电路的结合，使机器人能够实时感知环境中的有毒气体，从而采取相应措施保护被困人员免受有毒环境的伤害。由人工智能算法和硬件电路驱动的多模态电子皮肤具有强大的环境感知和信息处理能力，作为与物理世界交互的界面，极大地拓展了智能机器人的应用场景。

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.
