Vital signs monitoring using a new flexible polymer integrated PPG sensor

In this paper, we assessed feasibility of using Photoplethysmography (PPG) signal from flexible biosensor as an alternative solution to ECG for monitoring of cardiovascular and pulmonary performance. The potential advantage of this methodology is reduction in power consumption and improvement of complexity of body worn wireless multisensory platform for human physical activity and vital sign monitoring Hence, we propose an alternative mechanically flexible device for monitoring, Photoplethysmography (PPG) and computationally inexpensive algorithm for extraction of cardiovascular and pulmonary performance form the recorded PPG signal. The respiration rate was obtained from finger and forehead of ten healthy subjects and compared to reference methods using Bland and Altman methodology.
