According to U.S. Census Bureau, worldwide average of
infant mortality rate is 90, meaning that 90 infants die per
1000 live births within one-year period after birth. The
leading causes are stated as birth defects, preterm birth,
maternal complications of pregnancy, sudden infant death
syndrome (SIDS) and injuries (e.g. Suffocation).
Considering SIDS and injuries, the rate increases because
of uneducated or/and unobservant parents in such cases,
infant chokes on vomit or due to misplacement infant
suffocate. This study aims to reduce death rates of infants
by monitoring them continuously. We created a wristband
for infants to monitor SpO2 and heart rate, which is cloud
integrated, to share patients’ status with their doctor. By
this way, doctor can lead parents to take required actions
in a controlled manner. Moreover, the device also has the
ability to create audible alarms to warn the parents in
case of a complication.

Background Information / Aim According to U.S. Census Bureau, worldwide average of infant mortality rate is 90, meaning that 90 infants die per 1000 live births within one-year period after birth. The leading causes are stated as birth defects, preterm birth, maternal complications of pregnancy, sudden infant death syndrome (SIDS) and injuries (e.g. Suffocation).

References Method Results Future Works For the future direction, we are planning to integrate an ECG circuit without changing the circuit size. In addition, skin colour and environmental factors should be eliminated further to increase efficiency. Also, since this equipment is an IOT device, it is required to provide sufficient patient-data protection and better battery management. [1] C.-Y. Huang, M.-C. Chan, C.-Y. Chen, and B.-S.

For the testing part, we tried several configurations which are only frequency domain analysis, only time domain analysis and both domain together. We correlated our data by using golden standard calibration equipment, and curve fitting methods. As a result, we found our calculation equations for different cases. To conclude, we found out that our method gives similar results with commercial pulse oximeters. We tried several methods to understand the measurement methods clearly. However, most methods seem to be similar and group around some topics. Although, many research relies on time domain analysis, frequency domain analysis is also beneficial for accuracy of the measurements. On this basis, we created a solution which make use of both frequency and time domain analysis. Also, we tried to improve wrist performance and measurement stability with multiple sensors.
