This paper presents a comparative study in
physiological monitoring between a wearable opto-electronic patch sensor
(OEPS) comprising a three-axis Microelectromechanical systems (MEMs)
accelerometer (3MA) and commercial devices. The study aims to effectively
capture critical physiological parameters, for instance, oxygen saturation,
heart rate, respiration rate and heart rate variability, as extracted from
the pulsatile waveforms captured by OEPS against motion artefacts when using
the commercial probe. The protocol involved 16 healthy subjects and was
designed to test the features of OEPS, with emphasis on the effective
reduction of motion artefacts through the utilization of a 3MA as a movement
reference. The results show significant agreement between the heart rates
from the reference measurements and the recovered signals. Significance of
standard deviation and error of mean yield values of 2.27 and 0.65 beats per
minute, respectively; and a high correlation (0.97) between the results of
the commercial sensor and OEPS. T, Wilcoxon and Bland-Altman with 95% limit
of agreement tests were also applied in the comparison of heart rates
extracted from these sensors, yielding a mean difference (MD: 0.08). The
outcome of the present work incites the prospects of OEPS on physiological
monitoring during physical activities.

This study presents
the use of a multi-channel opto-electronic sensor (OEPS) to effectively
monitor critical physiological parameters whilst preventing motion artefact
as increasingly demanded by personal healthcare. The aim of this work was to
study how to capture the heart rate (HR) efficiently through a
well-constructed OEPS and a 3-axis accelerometer with wireless communication.
A protocol was designed to incorporate sitting, standing, walking, running
and cycling. The datasets collected from these activities were processed to
elaborate sport physiological effects. t-test, Bland-Altman Agreement (BAA),
and correlation to evaluate the performance of the OEPS were used against
Polar and Mio-Alpha HR monitors. No differences in the HR were found between
OEPS, and either Polar or Mio-Alpha (both p > 0.05); a strong
correlation was found between Polar and OEPS (r: 0.96, p < 0.001);
the bias of BAA 0.85 bpm, the standard deviation (SD) 9.20 bpm, and the
limits of agreement (LOA) from −17.18 bpm to +18.88 bpm. For the Mio-Alpha
and OEPS, a strong correlation was found (r: 0.96, p < 0.001);
the bias of BAA 1.63 bpm, SD 8.62 bpm, LOA from −15.27 bpm to +18.58 bpm.
These results demonstrate the OEPS to be capable of carrying out real time
and remote monitoring of heart rate.

The ultra-lightweight
wearable Carelight sensor can be placed on various parts of body such as
chest, back, forehead, palm, finger and ear lop as shown in figure 1, unlike
the conventional PPG sensor that designed for particular place e.g., finger.
In addition, Carelight sensor provides reliable, remote and continuous
monitoring of a range of vital signs including Heart Rate (HR), Respiration
Rate (RR), Heart Rate Variability (HRV), Blood Pressure (BP), Body
Temperature (BT) and Oxygenation saturation levels (SpO2%). The Carelight
sensor incorporates multiple copies of illumination sources and several
different wavelengths to allow of measuring for different skin types, colours
and ages. Also, the Carelight sensor selects optimum illumination source /
wavelength combination for the best quality signal at each illumination
interval.

Enhancement Of
Absorption And Resistance Of Motion Utilizing A Multi-Channel Opto-Electronic
Sensor To Effectively Monitor Physiological Signs During Sport Exercise
|
|
ملخص المشاركة:
|
This study presents an effective engineering
approach for human vital signs monitoring as increasingly demanded by
personal healthcare. The aim of this work is to study how to capture critical
physiological parameters efficiently through a well-constructed electronic
system and a robust multi-channel opto-electronic patch sensor (OEPS),
together with a wireless communication. A unique design comprising
multi-wavelength illumination sources and a rapid response photo sensor with
a 3-axis accelerometer enables to recover pulsatile features, compensate
motion and increase signal-to-noise ratio. An approved protocol with
designated tests was implemented at Loughborough University a UK leader in
sport and exercise assessment. The results of sport physiological effects
were extracted from the datasets of physical movements, i.e. sitting,
standing, waking, running and cycling. t-test, Bland-Altman and correlation
analysis were applied to evaluate the performance of the OEPS system against
Acti-Graph and Mio-Alpha.There was no difference in heart rate measured using
OEPS and both Acti-Graph and Mio-Alpha (both p<0.05). Strong correlations
were observed between HR measured from the OEPS and both the Acti-graph and
Mio-Alpha (r = 0.96, p<0.001). Bland-Altman analysis for the Acti-Graph
and OEPS found the bias 0.85 bpm, the standard deviation 9.20 bpm, and the
limits of agreement (LOA) -17.18 bpm to +18.88 bpm for lower and upper limits
of agreement respectively, for the Mio-Alpha and OEPS the bias is 1.63 bpm,
standard deviation SD8.62 bpm, lower and upper limits of agreement, – 15.27
bpm and +18.58 bpm respectively. The OEPS demonstrates a real time, robust
and remote monitoring of cardiovascular function.

Physiological Monitoring
|
|
ملخص المشاركة:
|
Pulse oximtery based upon the PPG principle is
one of the most widely used groups of health assessment devices, and uses at
least two different wavelength lights to measure the level of oxygen
saturation (SpO2%) in the blood. The study aims to research into an effective
way to capture human critical physiological parameters, i.e. SpO2%, heart
rate and body temper- sure through a well contracted and a small size
wearable reflectance patch together with a real-time, reduce noise and secure
wireless.

Novel Yet
Effective Motion Artefact Reduction Method For Continuous Physiological
Monitoring
|
|
ملخص المشاركة:
|
This study presents a
non-invasive and wearable optical technique to continuously monitor vital
human signs as required for personal healthcare in today’s increasing ageing
population. The study has researched an effective way to capture human
critical physiological parameters, i.e., oxygen saturation (SaO2%), heart
rate, respiration rate, body temperature, heart rate variability by a closely
coupled wearable opto-electronic patch sensor (OEPS) together with real-time
and secure wireless communication functionalities. The work presents the
first step of this research; an automatic noise cancellation method using a
3-axes MEMS accelerometer to recover signals corrupted by body movement which
is one of the biggest sources of motion artefacts. The effects of these
motion artefacts have been reduced by an enhanced electronic design and
development of self-cancellation of noise and stability of the sensor. The
signals from the acceleration and the opto-electronic sensor are highly
correlated thus leading to the desired pulse waveform with rich
bioinformatics signals to be retrieved with reduced motion artefacts. The
preliminary results from the bench tests and the laboratory setup demonstrate
that the goal of the high performance wearable opto-electronics is viable and
feasible.

A Novel Method
For Learning Programming Code Solutions
|
|
ملخص المشاركة:
|
This method is a
combination of hardware and software that enables students to more easily
produce effective programming code in a reduced time. The platform is simple
to use as it provides a graphical user interface (GUI), on which students
simply need to pick the components from the onscreen tool box menu and drag
them onto the working space. The students do not need to write any syntax
coding.
