Abstract

In this study we proposed a device composed of dry electrode and dry adhesive medical patch for biopotentials measurement. The behavior of the dry adhesive with mushroom-shaped micropillars is characterized through normal and friction force test. The adhesion strength (~1.2 N/cm2) is comparable to acrylic medical patch, and the repeating cycle testing result demonstrates that the adhesion strength of dry adhesive medical patch is larger than that of acrylic medical patch. Moreover, the dry adhesive medical patch does not cause skin to turn allergic owning to its biocompatibility. The proposed device also is used to record electrocardiogram (ECG) with dry electrode. Compared with conventional wet electrode, the signal quality is outstanding. The QRS-complex and T-wave of ECG are clearly legible.
