Recent advancements in artificial intelligence have spurred growing interest developing innovative architectures for synapses. Among these, nanowires emerged as promising candidates creating lightweight, flexible, and energy-efficient However, achieving in-plane aligned growth of on flexible substrates poses a substantial challenge their integration into bendable This study introduces room-temperature solution-phase graphoepitaxial technique that facilitates the along hydrophilic nanogrooves polyvinyl alcohol films. scalable method obviates need complex vacuum systems bypasses constraints traditional lattice-matching epitaxy by leveraging surface topography to guide nanowire alignment. Devices incorporating tri-isopropylsilylethynyl pentacene exhibit wavelength-sensitive photoresponse mimic fundamental biological synaptic behaviors, including paired pulse facilitation spike-number-dependent plasticity. Furthermore, these devices demonstrate exceptional bending stability, maintaining consistent response even after 2000 bends at curvature radius 0.4 cm. The approach's versatility is further highlighted its applicability diverse organic arrays. By seamlessly integrating without requiring post-growth transfer assembly, this approach simplifies fabrication processes improves device durability. underscores transformative potential efficient strategy advancing conformable nanowire-based technologies.
