The invention provides a hygroelectric charging and power management system. The system comprises at least one single layer or a bilayer of flexible hygroelectric polymer stacked together in series to generate power on collision with a water molecule, and at least one rechargeable battery having an input terminal and an output terminal. The input terminal is electrically connected to the single layer or the bilayer of flexible hygroelectric polymer to receive and store the generated power. The system further comprises at least one charger module to modulate between the single layer or the bilayer of flexible hygroelectric polymer and the rechargeable battery. The system applies Pulse Width Modulation (PWM) on the charger module to balance real-time recharging of the battery and to ensure constant power supply to a device under active load.

A process of providing an antibacterial coating to the surface of an article including the steps of applying a layer of an antibacterial precursor layer to the surface of an article to which an antibacterial coating is to be applied, wherein said antibacterial precursor layer is a precursor from which the coating is to be formed; and directing a neutral molecular hydrogen flux from a neutral molecular hydrogen flux emission source towards the surface of the article. Upon impact of neutral hydrogen molecules on molecules at or on the surface of an article, the bonds of the antibacterial precursor layer are selectively ruptured, and wherein the selectively ruptured bonds cross-link with themselves or with other chemical moieties at said surface or a combination thereof, resulting an antibacterial coating being formed on the surface of the article.
