An automated quasi-continuous capillary refill timing device (2015)
Journal Article
Blaxter, L., Morris, D. E., Crowe, J. A., Henry, C., Hill, S. J., Sharkey, D., …Hayes-Gill, B. R. (in press). An automated quasi-continuous capillary refill timing device. Physiological Measurement, 37(1), https://doi.org/10.1088/0967-3334/37/1/83

Capillary refill time (CRT) is a simple means of cardiovascular assessment which is widely used in clinical care. Currently, CRT is measured through manual assessment of the time taken for skin tone to return to normal colour following blanching of t...

Multi-exposure laser speckle contrast imaging using a high frame rate CMOS sensor with a field programmable gate array (2015)
Journal Article
Sun, S., Hayes-Gill, B. R., He, D., Zhu, Y., & Morgan, S. P. (2015). Multi-exposure laser speckle contrast imaging using a high frame rate CMOS sensor with a field programmable gate array. Optics Letters, 40(20), https://doi.org/10.1364/OL.40.004587

A system has been developed in which multi-exposure Laser Speckle Contrast Imaging (LSCI) is implemented using a high frame rate CMOS imaging sensor chip. Processing is performed using a Field Programmable Gate Array (FPGA). The system allows differe...

A single-chip CMOS pulse oximeter with on-chip lock-in detection (2015)
Journal Article
He, D., Morgan, S. P., Trachanis, D., van Hese, J., Drogoudis, D., Fummi, F., …Hayes-Gill, B. R. (2015). A single-chip CMOS pulse oximeter with on-chip lock-in detection. Sensors, 15(7), 17076-17088. https://doi.org/10.3390/s150717076

Pulse oximetry is a noninvasive and continuous method for monitoring the blood oxygen saturation level. This paper presents the design and testing of a single-chip pulse oximeter fabricated in a 0.35 µm CMOS process. The chip includes photodiode, tra...

Performance of a condensed electrode patch compared to a diffuse electrode array for transabdominal fetal heart rate and uterine contraction monitoring: a preliminary report (2015)
Journal Article
Hayes-Gill, B. (2015). Performance of a condensed electrode patch compared to a diffuse electrode array for transabdominal fetal heart rate and uterine contraction monitoring: a preliminary report. American Journal of Clinical and Experimental Obstetrics and Gynecology, 2(3), 89-95

Objective: Intrapartum monitoring of the fetal heart rate (FHR), maternal heart rate (MHR) and uterine activity (UA) can be done noninvasively via adhesive electrodes on the parturient’s abdominal surface. This approach, requiring multiple electrodes...
