By using the existing integrated chip and equipment to perform segmented collection, collection of micro-energy in the environment and collection of micro-ampere-level current with extremely low power consumption is implemented, a threshold of energy collection unit is reduced, an application range of energy collection is enlarged, an environmental constraint of energy collection is broken through, and an application field of clean energy is expanded.

Abstract: A hybrid power supply method, a device and a micro-energy power supply based on micro-energy collection are provided. The method includes: collecting micro-energy and storing the collected micro-energy in an energy storage unit; awakening or starting a system after the energy storage unit reaches a startup power; turning into a power saving mode after the system is started, and switching to a reserve energy storage unit for power supply; supplying the energy acquired by micro-energy collection to the system for data interaction; and making the system turn into the power saving mode after data transmission is completed, and switch to the reserve energy storage unit for power supply. A hybrid power supply mode is adopted, where the environmental energy collection is a main power supply and the chemical battery is an auxiliary power supply, so as to ensure the all-day operation of the device.
