Prevenção da violência contra mulheres: prova de conceito de um dispositivo vestível para monitoramento de riscos cotidianos

Abstract

The everyday violence faced by women represents a serious social problem that demands innovative solutions. This work presents the development of a proof of concept for a wearable device focused on women’s safety, integrating embedded systems technologies, wireless communication, and geolocation. The device uses the ESP32 microcontroller connected to GPS sensors, accelerometer, gyroscope, and digital microphone for real-time monitoring and risk situation detection. The developed architecture comprises data collection through sensors, local processing by the ESP32, back-end development in Node.js for information management, MongoDB database implementation, and React front-end interface creation for visualization and control. The results demonstrate the technical feasibility of integrating multiple sensors into an alert system capable of detecting suspicious movements, capturing audio evidence, and tracking location in real time. The proof of concept combines automatic detection with manual activation, expanding the spectrum of functionalities compared to previous solutions. The physical prototype was developed using a custom printed circuit board, manufactured at the UFC Sobral Campus. It is acknowledged that improvements related to miniaturization, energy optimization, and validation in real scenarios are necessary before commercial viability. It is expected that this research will contribute as a starting point for initiatives aimed at reducing violence against women, demonstrating technology’s potential in promoting women’s safety and autonomy.
