Abstract

A waterproof physiological signal detection device includes at least one electrode pad, a waterproof base layer, at least one water absorption unit, and a waterproof top layer. The electrode pad is positioned on a top surface of the waterproof base layer, and a first receiving compartment formed therebetween. The water absorption unit is positioned in the first receiving compartment. The water absorption unit has a top engaging the electrode pad and s a bottom engaging the waterproof base layer. The waterproof top layer overlaps the waterproof base layer and forms at least one top layer opening that corresponds to and exposes the at least one electrode pad. An undersurface of a circumference of the top layer opening overlaps a circumference of a top surface of the electrode pad with a central portion of the electrode pad projecting through the top layer opening.
