Environmental pollution is an undeniable fact in our daily lives. The air pollution caused by industrial waste generation (gases/toxins) and by the combustion of fossil fuels is getting more and more serious
technology for powering IoTs (e.g., traditional chemical batteries) faces a significant challenge due to a limited lifetime and powering distance, and due to the wide demand from the broadly distributed sensor networks. It is, therefore, urgent to investigate self-powereddevices in order to promote the
