abstract = "Photoplethysmography (PPG) is a non-invasive technique that by means of light interactionwith the skin, allows extracting physiological parameters such as heart rate orblood oxygen saturation, among others. Due to factors such as body location, movement artifacts, contact pressure or temperature, the PPG signal gets easily distorted. This distortion limits the use of this technique for constant monitoring. In this study, it is presented novel PPG sensor structures that aim to improve the acquisition robustness so that photoplethysmography can be used for constant multi-modal physiological sensing. Following the {\textquoteright}banana region{\textquoteright} theory, that defines the interaction of light with skin, the source-emitter distances and the number of components in the sensor were optimized for green and red light. Additionally, it is suggested that the sternum would be the ideal body location for constant monitoring.",
