According to @ai_darpa, Japan is implementing piezoelectric tiles in high-footfall locations such as Shibuya Crossing and Tokyo Station to capture mechanical energy from pedestrian traffic and convert it directly into electricity. This technology, often integrated with AI-powered data analytics, enables real-time monitoring and optimization of energy collection, contributing to urban sustainability initiatives. The practical application of AI-enhanced energy harvesting offers business opportunities for smart city infrastructure, energy management platforms, and IoT ecosystem providers seeking to enter or expand in the Asian market (source: @ai_darpa, Dec 25, 2025).
