Description

technical field [0001] The invention relates to a wireless self-gathering corrosion monitoring node powered by a weak heterogeneous source. Background technique [0002] The steel-concrete structure is one of the main structural types that will be used for a long time now and in the future. The corrosion of steel bars is the main reason for the reduction of the durability of the steel-concrete structure. According to the statistics of the World Corrosion Organization (WCO) in 2009, the global economic loss caused by corrosion exceeds 2.2 trillion U.S. dollars per year. Recently, my country has once again invested trillions of dollars in the development of infrastructure construction, accounting for a considerable proportion of major steel-concrete structure durability issues, which is bound to become a strategic issue affecting national economic development and social harmony and stability. The harm of steel bar corrosion is far greater than expected. With the further deter...
