Journal Article
Kapaya, H., Broughton Pipkin, F., Hayes-Gill, B., & Loughna, P. V. (2016). Circadian changes and sex-related differences in fetal heart rate parameters. Maternal Health, Neonatology and Perinatology, 2(1). https://doi.org/10.1186/s40748-016-0037-6

BACKGROUND: Previous researchers have studied circadian changes in the fetal heart rate (FHR) on small sample sizes and in a strictly controlled environment. This study was undertaken to investigate these changes during the late second and third trim... Read More about Circadian changes and sex-related differences in fetal heart rate parameters.

Presentation / Conference Contribution
Correia, R., Blackman, O. R., Hernandez, F. U., Korposh, S., Morgan, S. P., Hayes-Gill, B. R., James, S. W., Evans, D., & Norris, A. (Eds.). (2016). Highly sensitive contact pressure measurements using FBG patch in endotracheal tube cuff [Edited Proceedings]. Sixth European Workshop on Optical Fibre Sensors, Limerick, Ireland. https://doi.org/10.1117/12.2236859

A method for measuring the contact pressure between an endotracheal tube cuff and the trachea was designed and developed by using a fibre Bragg grating (FBG) based optical fibre sensor. The FBG sensor is encased in an epoxy based UV-cured cuboid patc... Read More about Highly sensitive contact pressure measurements using FBG patch in endotracheal tube cuff.

Motion limitations of non-contact photoplethysmography due to the optical and topological properties of skin (2016)
Journal Article
Butler, M. J., Crowe, J. A., Hayes-Gill, B. R., & Rodmell, P. I. (2016). Motion limitations of non-contact photoplethysmography due to the optical and topological properties of skin. Physiological Measurement, 37(5), N27-N37. https://doi.org/10.1088/0967-3334/37/5/N27

Non-contact photoplethysmography (PPG) provides multiple benefits over in-contact methods, but is not as tolerant to motion due to the lack of mechanical coupling between the subject and sensor. One limitation of non-contact photoplethysmography is... Read More about Motion limitations of non-contact photoplethysmography due to the optical and topological properties of skin.

Comparison of laser Doppler and laser speckle contrast imaging using a concurrent processing system (2016)
