Real-Time Physiological Monitoring in the Next Generation eHealth Network

Real-Time Physiological Monitoring in the Next Generation eHealth Network

Robust against noise from physical movement, multi-wavelength optoelectronic patch sensors (mOEPS) can provide comprehensive real-time physiological parameters and vital signs.

Our Aim

Fitness trackers are becoming increasingly popular as their capabilities continue to improve year on year. There is little doubt of the potential transformative power of these devices and it is easy to envision that soon these devices will not only vibrate to let you know you have reached your 10,000 steps goal for the day but also to warn you of high blood pressure, dehydration or risk of asthma attack due to poor air quality around you. Indeed, these devices have the potential of saving lives, diagnose illnesses and keep doctors constantly updated.

Modern devices already include heart rate monitors and even ECG sensors. At present, however, they suffer from motion artefacts that limit their accuracy and prevent their use in clinical settings. In this project, we explore the use of multi-wavelength optoelectronic patch sensors (mOEPSs) to overcome this limitation and be able to acquire accurately physiological and vital signs even during physical exercise.

mOEPSs combine optical and electrical measurements with real-time dynamic adapted filtration algorithms to provide a robust solution that is insensitive to physical motion. The technology compares favourably with commercial devices and the multi-wavelength illumination provides additional functionality such as the ability to measure peripheral capillary oxygen saturation (SpO2).

Besides its obvious application in the field of personal healthcare where mOEPSs provide a cost-effective solution to obtain comprehensive vital signs recordings, mOEPSs have also a direct application in sport physiological monitoring and assessment during physical activity.

Our Research

The project uses the facilities available in the Wolfson School of Mechanical, Electrical and Manufacturing Engineering, including the Photonics Engineering and Health Technology Lab with access static bikes and treadmill machines, multi-wavelength optoelectronic patch sensors (mOEPS), smart phone and smart watch devices.

Our Outcomes

This project promises a robust and cost-effective system to reliably measure physiological parameters and vital signs regardless of the user’s physical movements. Given the sports tradition at Loughborough University, the solution based around multi-wavelength optoelectronic patch sensors and state-of-the-art real-time signal processing is being targeted at sport physiological monitoring and assessment of athletes.
