Scientists have developed a groundbreaking wearable ultrasound patch, named UPatch, capable of continuously monitoring foetal health in the womb. Current ultrasound techniques are limited, often leading to false alarms and restricted to hospital visits. In contrast, UPatch allows for real-time tracking of the baby's heart rate and blood flow, capturing data continuously and anywhere. Prof. Sheng Xu from Stanford University emphasized that this device can provide a comprehensive view of the baby's condition, potentially leading to better diagnoses and interventions. Tested in trials across the US and UK, UPatch demonstrated close correlation with conventional ultrasound devices. Notably, it played a crucial role in a case of intrauterine growth restriction, prompting a necessary caesarean delivery. The team is now focused on developing a wireless version for everyday use, which could be particularly beneficial in low-resource settings. Dr. Antoniya Georgieva from the University of Oxford highlighted the significant potential of UPatch to prevent stillbirth and enhance understanding of foetal health.
