Abstract: Continuous monitoring of vital signs has become increasingly im- portant for digital healthcare and enhancing self-awareness. Wearable devices like smartwatches, earbuds, and rings are gaining widespread acceptance for health monitoring. However, two significant challenges remain: (i) the limited battery life of these devices makes them unsustainable for long-term use, and (ii) many older adults, who would benefit most from health monitoring, often face barriers due to limited digital literacy. To address these issues, we introduce BioPulse—a perpetual, patch form-factor device designed for continuous monitoring. BioPulse estimates key parameters for cardiac health such as heart rate, heart rate variability, and blood pressure. By utilising a sparse sampling algorithm alongside NFC- based energy transfer and communication, the system operates without a battery, achieving a 57.9% reduction in power consumption. The system demonstrates a mean absolute error of 5.6 mmHg for systolic blood pressure (SBP) and 4.5 mmHg for diastolic blood pressure (DBP) compared to the ground truth device. This combination ensures a more sustainable and accessible solution for vital signs monitoring
