High performance brain computer interface using dry electrode

Brain-computer interface (BCI) is a promising technology to bridge the human brain to external world, which is a novel communication method between human and computer or machine. BCI has been proved a useful technology for neural rehabilitation with growing evidence of the positive impact. Recently, some clinical studies has showed the efficiency of BCI technology in therapies for motor and cognitive diseases, including stroke, spinal cord injury, amyotrophic lateral sclerosis and attention-deficit hyperactivity disorder (ADHD). Among various BCI technologies, non-invasive BCI based on scalp electroencephalography (EEG) is the most commonly used for neural rehabilitation.

To apply EEG based BCI in neural rehabilitation, one of key issues is the use of wearable and dry electrode. The use of dry electrode BCI is with advantage of user-friendly and comfortable, but with limitation of poor signal quality and rare number of channels. Another issue is the BCI performance to fast and accurate identification of user’s brain activity. Information Transfer Rate (ITR) is a universal evaluation for BCI performance, in combination of speed and accuracy. EEG based BCI using dry electrode would encounter poor signal to noise ratio (SNR), requiring longer period of EEG signals to decode accurate intention so as to reduce the ITR.
