EEG-Pen for medical emergencies.

: This paper deals with a handy, mobile emergency EEG device. It provides a direct and immediate access to patients brain activity. This EEG-Pen consists of spring-loaded electrodes and all necessary components. Current mobile EEG systems do not seem to be appropriate for emergencies since they require a lot of time-consuming preliminary work. Usually the skin has to be pre-treated, the electrodes and the wires have to be attached to the body. This prototype of an EEG-Pen would do away with such preliminary measures and therefore becomes an essential tool for emergencies. Good recordings have been obtained. A miniaturized EEG-Pen, which can be easily carried by physicians or medical staff and immediately be used as a "bioelectric signal detector", requires more research.
