The National "14th Five-Year Plan" and the Outline of the 2035 Vision Goals propose to "build a modern infrastructure system that is complete, efficient, practical, intelligent, green, safe and reliable." The integration of infrastructure and energy is an important connotation of modern innovation and development, and an important way to achieve my country's "dual carbon" goal. The development of smart transportation, smart cities, etc. relies on widely distributed sensors, and one of the key issues of sensor network is energy supply. The battery power supply currently used faces problems such as short life, difficulty in maintaining, and environmental pollution. Cable transmission also has the disadvantages of high cost and space occupancy. How to collect various forms of energy from the environment to replace or extend the life of traditional batteries has attracted widespread attention from the industry and academia.
piezoelectric conversion mechanism
mechanical energy (waves, water flow, wind, vehicle driving, equipment operation, bridge vibration, human body movement, etc.) is one of the most common energy in the environment. Converting mechanical energy in the environment into electrical energy can realize self-energy sensing, control and driving, and has the advantages of flexibility, convenience and sustainability. However, mechanical energy acquisition technology still has some key problems, such as low output power of the device, single adaptation to the environment, and low reliability. Therefore, studying mechanical energy acquisition technology has urgent practical needs and broad application prospects.
piezoelectric energy acquisition kinetic design example
piezoelectric energy acquisition power density and flexible design, and has become one of the main ways to convert mechanical energy into electrical energy. At present, piezoelectric energy collection is an international hot research issue, but mechanical energy in the environment is generally dispersed, disordered and low energy density, and the working conditions may be very harsh, which brings huge challenges to the design of piezoelectric energy collection system. In order to solve the basic theoretical problems that restrict the development and application of piezoelectric energy acquisition technology, the Zhang Wenming research team has been committed to the design, dynamic analysis and control of piezoelectric energy acquisition for many years, and has achieved a series of original results. In order to summarize and disseminate the research results of piezoelectric energy acquisition dynamic design, it has written and published a monograph "Theory and Technology of Piezoelectric Energy Acquisition Dynamic Design". The book has been funded by the National Science and Technology Academic Books Publishing Fund.
