Charlton P, Kotzen K, Mejia-Mejia E, Aston P, Budidha K, Mant J, et al.
Physiol Meas
. 2022 Jul;
43(8).
PMID: 35853440
The photoplethysmogram (PPG) signal is widely used in pulse oximeters and smartwatches. A fundamental step in analysing the PPG is the detection of heartbeats. Several PPG beat detection algorithms have...

Sensors (Basel)
. 2021 Apr;
21(5).
PMID: 33800350
Near Infrared (800-2500 nm) spectroscopy has been extensively used in biomedical applications, as it offers rapid, in vivo, bed-side monitoring of important haemodynamic parameters, which is especially important in critical...

Sci Rep
. 2020 Oct;
10(1):16905.
PMID: 33037265
Biochemical and medical literature establish lactate as a fundamental biomarker that can shed light on the energy consumption dynamics of the body at cellular and physiological levels. It is therefore,...

Annu Int Conf IEEE Eng Med Biol Soc
. 2020 Oct;
2020:2618-2621.
PMID: 33018543
Heart rate variability (HRV) is a noninvasive marker of cardiac autonomic activity and has been used in different circumstances to assess the autonomic responses of the body. Pulse rate variability...
