Epilepsy is a major global health issue, affecting over 50 million people and significantly impairing daily activities if seizures go undetected and untreated. Current wearable seizure detection systems often lack multisensor capabilities, leading to reduced sensitivity and higher false discovery rates. This study aimed to create an efficient, cost-effective, real-time pediatric seizure detection device. The device integrates multiple sensors, including an accelerometer, to monitor body movement, heart rate variability, oxygen saturation, and jerky movements. Seizure detection is based on predefined thresholds for these metrics. The prototype was rigorously tested for accuracy, cost-effectiveness, and usability, with satisfactory results. It achieved acceptable accuracy in sensor measurements and was affordable to assemble. The device met its design criteria, confirming the effectiveness of the scientific procedures used in seizure identification. This device represents a significant advancement in pediatric epilepsy treatment, especially in resource-limited settings, by enabling accurate seizure detection and timely caregiver notification. Its implementation could mitigate complications related to pediatric epilepsy, allowing patients and caregivers to live more independently and reducing response times during seizures, thus minimizing the potential consequences of untreated epileptic episodes.
