Journal Article
Gomez, D., Morgan, S. P., Hayes-Gill, B. R., Correia, R., & Korposh, S. (2018). Polymeric optical fibre sensor coated by SiO2 nanoparticles for humidity sensing in the skin microenvironment. Sensors and Actuators B: Chemical, 254, 887-895. https://doi.org/10.1016/j.snb.2017.07.191

The sensitivity of a low-cost polymeric optical fibre humidity sensor based on transmittance changes due to evanescent wave absorption is reported using test measurements in an environmental chamber and of the skin. The layer-by-layer method was used... Read More about Polymeric optical fibre sensor coated by SiO2 nanoparticles for humidity sensing in the skin microenvironment.

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.

Forehead reflectance photoplethysmography to monitor heart rate: preliminary results from neonatal patients (2014)
Journal Article
Grubb, M., Carpenter, J., Crowe, J. A., Teoh, J., Marlow, N., Ward, C., …Hayes-Gill, B. R. (2014). Forehead reflectance photoplethysmography to monitor heart rate: preliminary results from neonatal patients. Physiological Measurement, 35(5), https://doi.org/10.1088/0967-3334/35/5/881

Around 5%–10% of newborn babies require some form of resuscitation at birth and heart rate (HR) is the best guide of efficacy. We report the development and first trial of a device that continuously monitors neonatal HR, with a view to deployment in...
