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.

Highly sensitive contact pressure measurements using FBG patch in endotracheal tube cuff (2016)
Journal Article
Correia, R., Blackman, O. R., Hernandez, F. U., Korposh, S., Morgan, S. P., Hayes-Gill, B. R., …Norris, A. (2016). Highly sensitive contact pressure measurements using FBG patch in endotracheal tube cuff. Proceedings of SPIE, 9916, Article 99161F. 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)
