Abstract
A biomedical electric wave sensor includes a base, a central pole, a dry electrode, a case, and a plurality of ribs. When the central pole lowers down, the ribs radiate and expand outward to push aside the hair of a subject, and the dry electrode exposes from the case and contacts the skin of the subject to measure a physiological electric wave signal from the subject. The present invention may overcome the intervention problem caused by hair and achieve the measurement of biomedical electric wave signal.
Claims15
A biomedical electric wave sensor, comprising:
- a base comprising a plurality of holes at a rim of the base, wherein a lower surface of the base is configured as a dry electrode;
- a case housing the base and exposing the lower surface of the base;
- a central pole connected to an upper surface of the base, penetrating through the case and configured for lifting and lowering relative to the case;
- and
- a plurality of ribs configured at an inner side of the case corresponding to the holes, the ribs radiating inward relative to the central pole, penetrating through the holes and protruding from the lower surface of the base, wherein as the central pole lowers down, the ribs protruding from the lower surface of the base radiate and expand outward to push aside hair of a subject, and the dry electrode is exposed from the case and contacts skin of the subject to measure a physiological electric wave signal from the subject.
