Improved physiological signal detection device

摘要

A physiological signal detection device (1) includes at least one electrode pad (11), a base layer (20), and at least one water absorption unit (30). The electrode pad is positioned on a top surface of the base layer. The electrode pad and the base layer form a first receiving compartment (S1) therebetween. The water absorption unit is positioned in the first receiving compartment. The water absorption unit has a top engaging the electrode pad, and the water absorption unit has a bottom engaging the base layer.
