Epilepsy is a common neural disorder disease; about 1.7% 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 have some seizures, 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 develop of the smart headband for epileptic seizure detection. The headband consists of a textile headband with flexible print circuit (FPC) inside, and fabric electrodes on it. The whole system includes the following circuits: an analog front-end circuitry for electroencephalography (EEG) record, an epileptic seizure detection System-on-Chip (SoC), and a Bluetooth Low Energy (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.
