Abstract

In this study, a multifunctional composite membrane is developed for advanced robotic skin applications, combining strain sensing, EMI shielding, and flame/explosion resistance. The membrane is fabricated by coating copper onto woven polyester fabric, followed by a layer of cobalt oxide-doped polyurea. This structure achieves high tensile strength (∼40 MPa), a Young's modulus of ∼328 MPa, and excellent flexibility. The composite membrane exhibits stable strain response, EMI shielding effectiveness up to 34 dB (X-band), and dominant absorption characteristics. Enhanced flame retardancy and explosion resistance result from the synergistic effects of the copper network and PU coating, which enable thermal insulation and protective char formation. These integrated properties make the copper-deposited fabric reinforced with CoO-doped polyurea a promising candidate for robust, lightweight robotic skins operating in harsh environments.

集成柔性复合材料的机器人皮肤应用与传感，电磁干扰屏蔽，和火焰/防爆

在这项研究中，开发了一种多功能复合膜，用于先进的机器人皮肤应用，结合了应变传感，EMI屏蔽和阻燃/防爆性。该膜是通过在编织聚酯织物上涂上铜，然后涂上一层氧化钴掺杂的聚脲来制造的。该结构具有高抗拉强度（~ 40 MPa）、杨氏模量（~ 328 MPa）和优异的柔韧性。该复合膜具有稳定的应变响应、高达34 dB （x波段）的电磁干扰屏蔽效果和显著的吸收特性。铜网和PU涂层的协同作用增强了阻燃性和防爆性，从而实现了隔热和保护炭的形成。这些综合性能使掺杂钴的聚脲增强的铜沉积织物成为在恶劣环境下运行的坚固，轻质机器人皮肤的有希望的候选者。
