A Home-based Epileptic Seizure Detection System Using Wearable and Non-contact Sensors

To address the issue of daily monitoring epileptics, we designed this multi-sensor seizure detection system, which contains a bracelet and a non-contact night monitor. The bracelet has an electromyography (EMG) sensor, a 3-dimensional accelerometer (ACM), and a 3-dimensional gyroscope. The non-contact night monitor contains a Doppler radar sensor. This designed approach proved a sensitive and convenient monitoring method for epileptics with convulsive seizures, especially those who had more seizures at night while releasing their caregivers from accompanying the patients all day long. Moreover, this study also provided a new recording method for medical clinical diagnosis. Clinical relevance — This proposed system could accurately estimate respiration, heartbeat rate, heart rate variability (HRV), and movement information to detect and alarm seizures.
