The integration of technology into urban infrastructure has led to innovative concepts in public furniture, including the emerging idea of park chairs capable of detecting electromagnetic field (EMF) waves. While not yet commonplace, prototypes and conceptual designs for such smart benches have been developed by technology companies and urban design researchers. These specialized chairs typically incorporate EMF sensors that can measure the strength of electromagnetic radiation from various sources, including cellular networks, Wi-Fi signals, and other wireless technologies. The data collected is often displayed through built-in digital interfaces or transmitted to municipal monitoring systems. The primary purpose of these innovative installations is to raise public awareness about EMF exposure levels in urban environments while providing valuable information for city planners and researchers. Some designs even incorporate shielding materials that can create low-EMF zones within public spaces. As cities become increasingly connected through 5G networks and IoT devices, the development of EMF-detecting park furniture represents an interesting convergence of urban design, public health awareness, and environmental monitoring technology.
