The research presented the extremely high potential of IoT-based biosensors to revolutionise diabetes treatment in India. With real-time constant monitoring of blood glucose levels, the sensors can have the capacity to empower patients to achieve better evidence-based self-management. This study examined awareness and uptake of Indian diabetic patients towards embracing such equipment, the benefits they accrue from it, and challenges that are associated with mass adoption. Special attention was given to distinguishing between the urban and rural environments and the influence of digital literacy, socio-economic status, and cultural beliefs towards uptake. A mixedmethod design was employed that integrated quantitative survey answers of 151 patients with qualitative open-ended responses. The respondents were adult patients with Type 1 or Type 2 diabetes who had ever used or were exposed to IoT-based biosensors such as Freestyle Liber, BeatO, or Bionime. Quantitative measures revealed trends in use/ level of satisfaction and outcomes experienced, while repeated themes tended towards identified barriers and user experience. It was proven that the patients cherished the potential of the biosensors to monitor noninvasively and in real-time blood sugar levels in the body, detect anomalous fluctuations, and directly assist the health care practitioners. The majority of the participants exhibited superior disease insights, an earlier treatment adjustment, and self-management confidence. Pre-existing social culture that favoured doctor-directed care also worked, mainly among older and less technologically inclined population groups. The study ends with the reflection that the biosensors made using IoT are already performing well as the tools of monitoring diabetes and have already been adopted by multiple users, still, multi-dimensional intervention would be critical in order to ensure sustainable adoption at the country level. These include subsidies by the government or insurance, training programs that hold cultural relevance, connectivity within rural areas, interfaces in local languages, and inclusion within the national health missions like the ABDM. The potential of IoT biosensors as the cheapest and patient-centred devices that will help overcome the diabetic burden in India can be popularised by overcoming technological and social-cultural barriers that arise.
