Development of respiration monitoring system for infants using ultrasensitive strain sensor patch

This study presents the development of a cost-effective, non-invasive system for synchronized artificial respiration to support preterm infants with underdeveloped lungs. Synchronizing airflow with the infant’s natural breathing cycle is crucial for efficient respiratory support. To achieve this, we developed a stretchable, skin-like, sensor array using screen printing on Silpuran substrate. The sensor’s ultrasensitive, multielement design enabled detection of subtle, multidirectional strain, produced by breathing. These signals were filtered and processed using advanced electronics to generate precise trigger points for real-time synchronization of artificial ventilation with the infant’s natural breathing pattern. The system was tested on a dummy, where airflow from a diaphragm (ventilator) was controlled and synchronized with simulated breathing (dummy). This non-invasive mechanism can provide continuous monitoring, ensure safer respiratory support for infants and a potential alternative to traditional invasive incubation methods.
