We propose a new structure consisting of a piezoelectric spring-mass system as a low-frequency piezoelectric energy harvester. A theoretical model is developed for the system from the theory of piezoelectricity. An analysis is performed to demonstrate the low-frequency nature of the system. Other basic characteristics of the energy harvester, including the output power, voltage, and efficiency, are also calculated and examined.

Electronic devices cover a large subset of daily life gadgets which use power to run, hence increasing the load of the energy needs and indirectly impacting greenhouse gas emissions. Smart electrochromic windows provide a solution to this through remarkable energy saving by adjusting optical behavior depending on the environmental conditions. Since the electrochromic windows also need power to run, a self-powered electrochromic panel will be a better solution.

Rural areas in Ethiopia serve as the primary source of charcoal for urban populations, mainly produced using traditional kilns. However, this traditional method significantly contributes to greenhouse gas (GHG) emissions, exacerbating climate change and deforestation. While banning charcoal production is not currently feasible in Ethiopia because of the lack of affordable alternative energy sources (fuel), improving the efficiency of the traditional production system can mitigate the climate impact caused by charcoal production.

Photosynthesis in nature begins with light harvesting. The special pigment-protein complex converts sunlight into electron excitation that is transmitted to the reaction center, which triggers charge separation. Evidence shows that quantum coherence between electron excited states is important in the excitation energy transfer process.

Herein, a flexible rolling triboelectric nanogenerator with a bionic gill cover structure (GFR-TENG) to harvest steady low-velocity water flow energy is proposed. The dielectric material of the GFR-TENG is eight flexible hollow fluorinated ethylene propylene (FEP) pipes, which guarantees that rolling friction is formed between the dielectric material and copper electrode.
