Personal safety is a pressing issue, particularly for women and teenage girls, who face elevated risks in both public and private spaces [1]. Traditional safety devices and smartphone apps are often unreliable due to connectivity issues, ease of confiscation, or conspicuous designs. To address these challenges, we developed SafeLink, a discreet smart necklace integrating a Particle Boron microcontroller with LTE connectivity, a PA1010D GPS module, and an LSM6DSOX accelerometer/gyroscope [2]. Data is transmitted to Firebase, where it is accessed through a Flutter based mobile app that manages emergency contacts and provides real-time tracking. Experiments demonstrated that SafeLink performs reliably outdoors with minimal GPS error, though accuracy decreases indoors and in urban canyons [3]. Battery testing showed sufficient daily use but limited runtime in extended emergency scenarios. Compared with prior SMS-based child safety wearables, SafeLink improves responsiveness, automation, and usability. Ultimately, SafeLink provides a proactive, IoT-enabled solution that empowers women and teens with accessible, real-time personal safety technology.
