我们提出了一个完全封装的17毫米3的传感器节点，通过光捕获实现永久运行，低至179勒克斯。电池充电和管理电路是自启动的，并支持使用定制GaAs堆叠光伏电池对电池进行快速充电。它延迟充电，直到组装过程完成，以保护电池在充电时免受高温影响，并在运行前防止过早放电。
We propose a fully encapsulated 17-mm3 sensor node with perpetual operation enabled by light harvesting with as little as 179 lux. A battery charging and management circuit is self-starting and supports rapid charging of the battery with a custom GaAs stacked photovoltaic cell. It delays charging until the assembly process is complete to protect the battery from exposure to high temperatures while charged and premature discharge prior to operation.
