Epilepsy is a common neural disorder disease; about 0.5% of the global population has epilepsy . Most patients take antiepileptic drugs to reduce their seizures. Among them, nearly one-third of the patients are drug-resistant epilepsy. The alternative treatment is the resection surgery of removing the epileptogenic zone. However, all above patients will still suffer seizures occasionally, which will influence the patients' quality-of-life, and further introduce danger and inconvenience to patients and people around. This paper presents the design and development of the smart headband for epileptic seizure detection. The headband consists of a fabric headband with flexible print circuit (FPC) inside and fabric electrodes on it. The whole system includes the following circuits: an analog front-end circuitry, an epileptic seizure detection tag (ESDT), and a Bluetooth Low Power (BLE) chip. The result of designed circuits yields a compact and low-power design of smart headband for epileptic seizure detection which is suitable for wearable usage. The epileptic seizure detection algorithm is validated by Children's Hospital Boston-MIT (CHB-MIT) EEG database .
