specific Embodiment

[0031] The environmental electromagnetic wave energy harvester provided by the invention. The energy harvester is mainly composed of the following modules: antenna module 1, radio frequency matching module 2, energy conversion module 3, charge pump module 4 and the final charging object. Specific examples are as follows:

[0032] The first step in energy harvesting is to analyze the distribution of electromagnetic waves in space, and select a band with a larger space radiation field strength for reception, thereby extracting larger stable energy. Taking the environment as an example, the spectrum characteristic tester is used to test the energy distribution diagram of the electromagnetic wave spectrum in the environment where the antenna is erected, as shown in figure 2 shown. There are several peak points reflected in the figure. Further tests on the more powerful AM bands, such as image 3 As shown, the frequency band with the highest energy can be selected as the energ...

Abstract

The invention relates to an environmental electromagnetic wave energy acquirer which comprises an electromagnetic spectrum detection circuit and an antenna module, wherein the antenna module is connected with a radio frequency matching module; the radio frequency matching module is connected with an energy conversion module; the energy conversion module is connected with a charge pump module; and a charging circuit is arranged on the charge pump module. Electromagnetic waves are captured from a space environment to charge a hand-held mobile terminal through a voltage boosting circuit. The acquirer has the benefits that the electromagnetic waves in the space environment can be used for providing electric energy to the hand-held mobile terminal; when the collected electric energy is less, the power can be supplied for the hand-held mobile terminal in a sleep mode; when the electric energy is more, the acquirer can charge a lithium battery and be merged into a power network to supply the power for a circuit; therefore, the acquirer facilitates daily life and is an energy-saving scheme.

Description

technical field [0001] The invention relates to the technical field of mobile charging equipment, in particular to an environmental electromagnetic wave energy collector and its application. Background technique [0002] With the continuous progress of society and the continuous development of science and technology, people are now more and more concerned about the earth on which we live, and most countries in the world have fully realized the importance of the environment to our human development. All countries are taking active and effective measures to improve the environment and reduce pollution. The most important and urgent issue is the energy issue, and energy has become one of the key issues restricting the development of the world economy. The fundamental way to solve the energy problem is to develop and utilize environmentally friendly new renewable energy. There are various energy sources in the environment we live in. Commonly used environmental energy sources ...
