Safe-Sign / Signboards


After extended periods in the sun and rain, old signs can be unstable and threaten the safety of passersby. It is difficult to tell whether signs are secure, with people oblivious of the danger until the sign falls down. Safe-sign is an electronic sign comprising e-paper and equipped with pressure sensors at the top and bottom. When the pressure sensors detect changes in weight, the sign displays a warning to the store owner and passersby, reducing the possibility of accidents and ensuring safety. The e-paper makes it easy for store owners to change their signs and display the latest information, thereby increasing information exposure.
