To overcome the drawbacks in cuff based bp monitors, a new method for measuring BP has been proposed, which does not require a cuff. By using this approach, individuals can avoid the potential inaccuracies associated with cuff-based BP monitors and obtain more reliable. BP readings. The important principle used in this device is PhotoPlethysmoGram (PPG) and electrocardiogram (EKG). PPG is a simple and affordable optical measuring technique that is frequently used for heart rate monitoring. Thus measures the volumetric fluctuations of blood circulation and we obtain our PPG signal data.  This device is also integrated with Clinical-grade ECG sensor(AFE) which provide highly accurate data. This device algorithm is designed to analyse the PPG and ECG signal and by comparing the peaks  of both the waves and using our model the systole and diastole values are obtained. Uniqueness in this device is we can get our results just with our fingertips neither cuff is placed to measure BP nor electrodes are placed in chest to detect ECG.
