Unlike hospital-based monitoring methods, our lightweight, portable, and cost-effective
solution offers continuous real-time monitoring, improving response times and overall patient safety.
Addressing key challenges such as power efficiency, false alarms, and latency in alert transmission, our research
contributes to the advancement of wearable healthcare technology for epileptic seizure detection and
emergency response.
[29,34,35]
The system activates an emergency response mechanism, which includes: Audible
Alert System – A DF-Player Mini module with a speaker generates a warning sound to alert nearby individuals.
Emergency SMS Notification – A GSM module (SIM800L/SIM900A) automatically sends an alert message to
caregivers, ensuring quick intervention. GPS Tracking for Emergency Location – A GPS module tracks the
patient’s location and shares it with caregivers in real time.
Compared to traditional hospital-based EEG monitoring, our system is designed to be lightweight, cost-
effective, and user- friendly, allowing patients to move freely while benefiting from continuous real-time
monitoring. This approach significantly reduces response time during seizures, making it an effective and
practical solution for epilepsy management. The primary contributions of this work include: Development of a
wearable, real-time epileptic seizure detection system with minimal intrusion into the patient’s daily life.
Integration of multi-sensor technology (motion and heart rate sensors) for accurate seizure detection.
Implementation of an emergency alert system combining audible alarms, SMS notifications, and GPS tracking
for immediate assistance. Optimization of power consumption to ensure prolonged battery life for
uninterrupted monitoring.
2. Literature survey
Epilepsy is a chronic neurological disorder characterized by recurrent and unpredictable seizures that pose
serious risks to patient health and safety.
[1,2]
Over the years, various seizure detection and alert systems have
been developed using physiological signals, motion sensors, and wireless communication technologies.
[3,4]
Existing seizure detection approaches can be broadly classified into EEG-based systems, motion-based systems,
physiological signal-based systems, and wearable IoT-based healthcare systems.
[5,14,24]
Early research by Shoeb
and Guttag demonstrated the use of electroencephalogram (EEG) signals combined with machine learning
techniques for seizure detection.
[7]
Although EEG-based systems provide high detection accuracy, they require
complex signal processing, clinical-grade equipment, and continuous monitoring, making them less suitable for
portable wearable applications.
[7,9,10,36,37]
To improve wearability and real-time monitoring, researchers explored
motion-based seizure detection using accelerometers and gyroscopes. Motion-based systems effectively detect
repetitive and high-amplitude body movements associated with seizure activity, but they often generate false
positives during normal physical activities such as running or sudden movements.
[4,5,21,30]
Physiological signal
monitoring has also gained considerable attention for seizure detection. Van Elmpt et al. reported significant
heart rate variations during seizure episodes, while Poh et al. demonstrated that physiological indicators such
as heart rate variability improve seizure detection reliability.
[12,13]
These approaches help identify abnormal
physiological changes that occur during epileptic events and enhance detection accuracy when combined with
motion analysis.
[32,38]
Recent advancements in wearable healthcare technology and IoT systems have enabled the development of
real-time remote seizure monitoring solutions. Wearable sensor-based healthcare systems provide continuous
physiological monitoring and improve patient mobility compared to traditional hospital-based monitoring
methods
.[5,15-18]
In addition, GSM-based emergency alert systems have been integrated into wearable healthcare
devices to send automatic notifications to caregivers during emergencies, ensuring timely medical
assistance.
[8,31]
Machine learning, deep learning, multimodal sensing, and adaptive IoT architectures have
further enhanced the reliability of seizure detection systems.
[22,35-39]
Recent studies have also demonstrated the
benefits of wearable digital health technologies, energy-efficient embedded systems, and clinical seizure
detection devices for long-term epilepsy monitoring.
[7,15,26,29,40-42]
These studies indicate that combining motion
sensing, physiological monitoring, machine learning, and wireless communication technologies can
significantly improve the reliability and effectiveness of wearable epileptic seizure detection systems.
2.1 Research gap
Despite significant advancements, existing systems suffer from limitations such as high false alarm rates,
incomplete physiological monitoring, and limited real-time alert capabilities. Most solutions rely on either
motion-based or physiological parameters independently, which fails to capture the complete characteristics
of seizure events.
2.2 Proposed-approach
To address these limitations, the proposed system integrates motion, heart rate, SpO₂, and EMG signals within
a wearable IoT platform. By employing a multi-sensor fusion approach along with real-time alert mechanisms
and GPS-based location tracking, the system improves detection accuracy, reduces false positives, and ensures
timely emergency response. Table 1 presents a comparison of existing seizure detection systems based on their
