On April 27th, a reporter from our outlet learned from Westlake University that a research team, led by Professor Kong Wei from the university's School of Engineering, has successfully achieved the high-quality integration of wafer-scale single-crystal molybdenum disulfide films onto flexible substrates. This significant advancement marks a transition from "wet" to "dry" transfer and integration techniques for single-crystal two-dimensional semiconductors, overcoming a key technological bottleneck in the development of high-performance flexible electronics. Employing an oxide-based dry transfer strategy, the researchers have managed to eliminate contact between the material and polymers, water, or organic solvents throughout the entire process, thereby effectively preserving the material's inherent properties. Leveraging this process, the flexible transistor arrays developed by the team have achieved remarkable performance breakthroughs, including ultra-high current on/off ratios, exceptional mobility, and superior gate control capabilities. These arrays have been successfully applied in active-matrix tactile sensing systems, enabling soft robots to perceive pressure distributions in real-time and showcasing potential applications in the fields of intelligent tactile sensing and electronic skin. The relevant research findings have been published in the esteemed journal Nature Electronics.
