SOLANE® is a road- and path-integrated guidance module that converts passive lane markings into solar-powered, machine-readable infrastructure. Built on SOFTPV's 1 mm-class three-dimensional SOFTCELL® platform, each unit harvests solar energy during daylight and stores it in an onboard battery. When ambient illuminance falls below a preset threshold, such as at night or in rain and fog, the module automatically powers color-adjustable LEDs through prism optics to create a uniform illuminated lane surface for boundaries, directions, hazards, and traffic instructions. Independently of lighting operation, SOLANE transmits positional, environmental, and operating data at scheduled intervals or in response to vehicle-passage events, supplementing onboard perception for connected vehicles and mobile robots. Its modular, replaceable architecture supports roads, airports, logistics facilities, parking areas, bicycle lanes, and pedestrian paths while reducing external power wiring and routine battery replacement.
