First Claim
Patent Images
1. 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.

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.
