本文提出一种用于飞行昆虫定位的微型无电池无晶振发射系统，采用28nm工艺的TX IC、定制天线、光伏电池和存储电容，在1.45km范围内实现0.9m定位精度。系统成功部署在活黄蜂上并验证了功能，为小昆虫/物体提供超低重量、长距离、高精度的无源追踪方案。
crystal-less localization tag with a 28nm TX IC, custom antenna, PV cells, and storage cap achieves 0.9m accuracy over 1.45km. Designed for tracking wasps, this system also enables unobtrusive monitoring of other small insects/objects. We deployed a tag on a live wasp and demonstrated full system functionality while the wasp was able to fly normally. The system achieves the longest range, highest long-distance accuracy, and lowest weight, with battery-free operation, among the stateof-the-art entries in the comparison table in Figure 35.2.6. In recent years, significant progress has been made in miniaturized tracking devices for new applications from equipment tracking to small animal studies. However, the ability to study the movements of small insects, such as honey bees and wasps, remains elusive
