Published in a <a href=\"http:\/\/dx.doi.org\/10.1007\/s40820-025-01724-1\">Nano-Micro Letters<\/a>, this work highlights silicon\u2019s untapped potential for soft, deformable applications.<\/p>\n\n\n\n<p>Crystalline silicon, a cornerstone of traditional electronics, faces limitations in soft electronics due to its rigidity. However, geometry engineering overcomes this by reshaping silicon into 2D thin films and 1D nanowires (SiNWs). These nanostructures exhibit remarkable flexibility, sustaining tensile strains over 10%\u2014far surpassing bulk silicon.<\/p>\n\n\n\n<p>Key advancements include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Enhanced Performance:<\/strong>\u00a0SiNWs boast superior mechanical properties, including superplasticity and fracture toughness, while maintaining high electrical conductivity. Their large surface area also makes them highly sensitive to mechanical stress.<\/li>\n\n\n\n<li><strong>Innovative Fabrication:<\/strong>\u00a0Techniques like metal-assisted chemical etching (MACE) and vapor\u2013liquid\u2013solid (VLS) growth enables precise control over SiNWs\u2019 size and alignment. A newer method, in-plane solid\u2013liquid\u2013solid (IPSLS) growth, offers cost-effective, large-scale production of elastic SiNW structures.<\/li>\n<\/ul>\n\n\n\n<p>The team employed advanced tools like electron microscopy and Raman spectroscopy to characterize SiNWs, confirming their structural integrity and functionality.<\/p>\n\n\n\n<p><em>\u201cGeometry engineering bridges the gap between silicon\u2019s high performance and the flexibility demands of modern electronics,\u201d<\/em>&nbsp;explained Professor Yu.&nbsp;<em>\u201cThis opens doors for transformative applications, from healthcare monitors to brain\u2013machine interfaces.\u201d<\/em><\/p>\n\n\n\n<p>The review underscores silicon\u2019s future in soft electronics, calling for scalable production methods and exploration of biomedical uses like biosensors.
