This paper explores the practical implications of self-defence laws in India, with a particular focus on their application to women’s safety. It begins by outlining the legal definition and categories of self-defence—physical, verbal, psychological, and cyber—and examines key provisions of the Indian Penal Code (Sections 96–106) that govern the right to private defence. Through a comparative analysis of landmark legal cases, the paper highlights the nuanced boundaries between justified and excessive force, especially in gendered contexts. It then shifts to a real-world application by examining the current landscape of personal safety devices for women in India, identifying gaps in accessibility and effectiveness. Based on this analysis, the paper proposes a multifunctional, low-cost wearable safety bracelet designed for Indian women across socio-economic backgrounds. Ultimately, the study underscores the limitations of legal protection in the absence of awareness and immediate aid, and argues for innovative, preventive approaches to complement existing legal rights.
