Description
technical field [0001] The invention belongs to the technical field of environmental micro-energy collection and power generation, and specifically relates to a design method for a multi-source cascaded three-channel micro-energy collection and power generation platform with high power generation power, high energy storage level, and self-adaptive energy consumption matching capability. Background technique [0002] The development of MEMS and microelectronics technology promotes the application of more low-power wireless sensors in industrial field detection and online monitoring. "Passive" and "wireless" have always been the goals pursued by the progress of sensor technology. With the development of the Internet of Things and the widespread use of sensors, the battery-based wireless sensor power supply method has attracted much attention due to the inherent defects of batteries. Due to its small size and limited electric energy, it is difficult to realize "passive" in the...
