Circadian changes and sex-related differences in fetal heart rate parameters (2016)
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.

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)
Journal Article
Sun, S., Hayes-Gill, B. R., He, D., Zhu, Y., Huynh, N. T., & Morgan, S. P. (2016). Comparison of laser Doppler and laser speckle contrast imaging using a concurrent processing system. Optics and Lasers in Engineering, 83, https://doi.org/10.1016/j.optlaseng.2016.02.021

Full field laser Doppler imaging (LDI) and single exposure laser speckle contrast imaging (LSCI) are directly compared using a novel instrument which can concurrently image blood flow using both LDI and LSCI signal processing. Incorporating a commerc... Read More about Comparison of laser Doppler and laser speckle contrast imaging using a concurrent processing system.

Characterization and use of a fiber optic sensor based on PAH/SiO2 film for humidity sensing in ventilator care equipment (2016)
Journal Article
Hernandez, F. U., Morgan, S. P., Hayes-Gill, B. R., Harvey, D., Kinnear, W., Norris, A., …Korposh, S. (2016). Characterization and use of a fiber optic sensor based on PAH/SiO2 film for humidity sensing in ventilator care equipment. IEEE Transactions on Biomedical Engineering, 63(9), 1985-1992. https://doi.org/10.1109/TBME.2016.2521662

Objective: To develop a compact probe that can be used to monitor humidity in ventilator care equipment. A mesoporous film of alternate layers of Poly(allylamine hydrochloride) (PAH) and silica (SiO2) nanoparticles (bilayers), deposited onto an optic...
