This paper proposes an IoT-based framework for monitoring and reducing domestic violence in intimate relationships. Intimate partner violence negatively impacts relationship dynamics. To address this, we developed a prototype IoT-enabled wristband designed for couples. The wristband monitors physical and mental states, such as physiological parameters, mental status, stress levels, and behavioural patterns, using sensors that detect potentially hazardous behaviour. When the system detects a violent incidence, it examines the situation and sends alarm signals to the wearer while controlling the behaviour in question. Furthermore, if the situation worsens to the point of uncontrollability, such as physical hostility, the system notifies selected emergency contact persons such as family members, friends, police enforcement, or other relevant individuals whose information has been pre-registered with the device. The proposed approach intends to drastically reduce intimate partner violence, improve the quality of couple relationships, and increase overall safety. This revolutionary marriage band serves as a self-help tool for the individual to reduce their aggressive behaviour and acts as a safety weapon for the individual whose life might be in danger inside the relationship. The framework was developed, and data were collected in compliance with ethical guidelines and maintaining confidentiality. The participants included survivors of intimate partner violence, psychologists, data scientists, and legal professionals (advocates and police officers). The framework received overwhelming support from participants, they emphasized the device’s potential to prevent severe harm and fatalities in IPV situations. Unlike existing technologies that detect hypertension and mood swings, this device provides real-time alerts, enabling timely interventions and enhancing its life-saving potential.
