The laboratory for systems in close proximity to the person (LS2P) develops wearable devices for the monitoring of the physiological parameters such as the cardiac rhythm, the oxygen saturation of the tissue or the arterial pressure. High integration constraints are applied in the early design phases so that the resulting sensors can be integrated in wearables like wristband, patch or headband. The robustness of the measure is a key factor for the success of these devices. The design of the sensors and the performances of the algorithms for data processing are the main contributors of the quality of the measure. Understanding how the perturbations occurring in the daily life affect the human physiology is also crucial to develop efficient solutions. In the lab, the design of new devices relies on the use of numerical models simulating the human body. The PhD student, having a background in biomechanical engineering, will work in close collaboration with the team working on the virtual body. He/she will develop a 3D deformable model of the forearm including the blood perfusion of the tissue. Digital patterns will then be defined to quantify the effects of the perturbations induced by the position and the motion of the forearm. The conclusion will be validated by analyzing experimental data.
