When making an electrocardiographic (ECG) examination, there are some cases where satisfactory ECG recordings can not be taken due to extreme increase in resistance of bio-electrodes. To investigate the reason why the resistance increases extremely, the relationship between DC electrode resistance and the skin properties, especially the sweat glands on the human forearm, was studied. DC resistance was measured by a digital tester(test current 20nA) and the active sweat glands were detected by means of iodostarch reaction. The electrode resistance was greatly influenced by the widely open (active) gland pores right under the region of electrode application and it was found that the value of resistance was inversely propotional to the number of the active sweat glands. After warming the forearm, the number of the opening pores increased, and the value of resistance decreased. The effects of the epidermal exfoliation and sebaceous properties on the electrode resistance were minimal.
