Abstract
An active dry sensor module for measurement of bioelectricity is disclosed. The active dry sensor module of the present invention excludes the use of a conductive gel, thereby not supplying unpleasantness and discomfort to a reagent and preventing the interference of the signal due to a noise component. Further, the active dry sensor module of the present invention amplifies the biomedical signal to a desired level, thereby precisely and easily measuring the biomedical signal.
Claims9
An active dry sensor module comprising:
- a hollow main body having an upper surface with an insertion hole formed through the upper surface;
- a cap, interlocked with the insertion hole, having a uniform central internal cross section and an upper fringe protruded from the upper surface;
- an active electrode inserted into the cap so that the active electrode is slidable relative to the cap, the active electrode having a contactable upper surface and a latching protrusion protruded from a lower part of the active electrode that is capable of being latched onto a lower end of the cap;
- a resilient member with a first end contacting the lower part of the active electrode, installed in the main body, and electrically connected to the main body;
- and
- an amplification circuit, installed in the main body and coupled to a second end of the resilient member, that is capable of receiving and processing a biomedical signal passed through the spring from the active electrode.
