具有高空间分辨率的柔性和压阻式电子皮肤（E-skins）在人工智能和人机交互中非常受欢迎。在本研究中，我们发展了一种简单的方法，利用微影技术来图案化压阻层，以实现即时触觉感测与空间解析。采用反向模压法制备了基于聚甲基丙烯酸甲酯（PMMA）/多壁碳纳米管（MVVCNTs）的蜂窝孔阵列压阻层。该器件在低压区的灵敏度为88 kPa（-1）（
Flexible and piezoresistive electronic skins (E-skins) with high spatial resolution are highly desired in artificial intelligence and human-machine interactions. In this study, a simple method is developed to pattern a piezoresistive layer using lithography, which can realize real-time tactile sensing and spatial resolution. The piezoresistive layer with a honeycomb hole array based on polymethyl methacrylate (PMMA)/multiwalled carbon nanotubes (MVVCNTs) was fabricated using a reverse mold with a ZnO nanorod array. The device exhibits an ultrahigh sensitivity of 88 kPa(-1) in the low-pressure regime (
