We review the recent researches on structure-induced water collecting property of spider silk and bioinspired fibers. Since the capture silks of cribellate spiders have a unique wet-rebuilt structure with spindle-knots and joints for directional water collection, we are inspired to fabricate a series of artificial gradient micro-/nanostructure fibers. These fibers display excellent functions such as driving of tiny water drops in directions, water capturing, multi-gradient cooperation effect and wet-respond to humidity of environment as well. This review is helpful to design novel smart functional materials that can be extended to develop the device or system for water collection, sensor, fluid-controlling, filter and others
