Description

technical field [0001] The invention belongs to the application field of optoelectronic technology, and in particular relates to an integrated wireless sensor optoelectronic micro energy energy control system and method. Background technique [0002] With the development of microelectronics technology and MEMS sensor technology, the power consumption of MEMS wireless sensor nodes is getting smaller and smaller (power consumption in the active state is several mW, power consumption in the sleep state is tens of μW), and the time occupied by the active state is shorter , the node works in a dormant state for a long time. MEMS wireless sensor nodes are powered using traditional power technologies, which directly limit the miniaturization of wireless sensor nodes. In addition, considering that wireless sensor nodes are usually used to monitor the environment and toxic and harmful substances in remote areas, subsequent maintenance is more difficult. For this reason, converting ...
