Abstract
The present invention provides a dry electrode (A) for registering biopotentials of head hairy portion, the electrode (A) having the form of substantially a comb comprising teeth (B) connected with each other in electrically-conducting manner, whereby the length (c) of the teeth (B) is at least 70 percent of the electrode (A) length (b). This form enables an easy application of the electrode to the hairy portion of the head and at the same time allows for a good contact with the skin.
