a Schematic illustration of multiple mechanoreceptors in glabrous skin for accurate tactile perception. b Proposed chemistry of benzophenone inhibiting PDMS cross-linking under UV light to prepare prslPDMS layer. c Simple geometric analysis of micro-cage structure formed by prslPDMS under external pressure. d Two-dimensional deformation simulation analysis of the PDMS & prslPDMS and PET under external pressure, and the micro-cage structure of the former enables the small elongation strain compared with the latter. e Quantitative analysis of displacement variation along the x-axis for different models, and the displacement of adjacent pixel using prslPDMS layer decrease by 90.3% compared with PET. f Crosstalk isolation versus the ratio of spacer length to pixel length, the better isolation effect could be achieved when its value is greater than 1:2.
