Abstract

The invention discloses a direct-current droplet generator and a preparation method thereof. The generator is characterized in that the generator has a structure in which all electrodes are placed above a solid surface and do not need to be grounded, so that the direct-current liquid drop generator can be constructed on any surface including a block body, a thin film and a coating; the droplet generator structure comprises a solid hydrophobic surface, an upper electrode, a collector pin, a lower electrode, an upper electrode lead and a lower electrode lead. The solid surface is a hydrophobic surface made of any artificial or natural materials, the upper electrode and the lower electrode are placed on the solid surface at a certain interval, the current collecting needle can be of an independent conductive tip structure and can also be directly machined on the electrode, and the generator can collect electric energy by impacting the surface through liquid drops. Compared with the prior art, the direct-current droplet generator can be constructed on any solid surface, the collected liquid mechanical energy is converted into the electric energy with the direct-current characteristic, and the direct-current droplet generator has the advantages of being simple in preparation process and low in cost. The open-circuit voltage of the direct-current liquid drop generator is up to kilovolt, a power management circuit is not needed, and the direct-current liquid drop generator can directly drive micro electronic devices to work or charge an energy storage unit. The structure of the direct-current generator has the functions of power generation, rectification and energy storage at the same time, a new technology based on solid-liquid interface water energy collection is developed, and the practical progress of water energy collection is greatly accelerated; meanwhile, the device is also a sensor or a probe. Due to the fact that the device achieves effective separation of charges, the device has extremely high application value in the aspects of droplet energy collection and self-driven sensing.

Description

technical field [0001] The invention relates to the field of power generation technology and sensing, in particular to a universal power generation technology and power generation device based on a solid-liquid interface. Background technique [0002] Energy provides an inexhaustible source of power for the development of human society, and converting other forms of energy into efficient and controllable electrical energy is one of the important directions for the development of the energy field. The current power generation technology is still dominated by traditional fossil energy, which has brought about problems of climate change and environmental pollution that cannot be ignored. New energy technologies have arisen at the historic moment and have been vigorously developed. At present, they mainly include water energy, nuclear energy, solar energy, wind energy and other technologies, which have broad application prospects. Among them, water covers 71% of the earth's sur...

Problems solved by technology

The introduction of power management circuits will inevitably increase the complexity of the water energy harvesting system, which will not only increase additional circuit energy loss, reduce portability and stability, but also greatly increase the cost

Therefore, the current water energy harvesting power generation system still has a very big challenge to the actual application.
