In biomedical applications, direct current (DC) is typically avoided due to safety concerns related to its effects on the human body. DC creates a continuous flow of electrical current in one direction, which can lead to sustained muscular contractions and potentially cause serious injuries such as burns or cardiac arrhythmias. This is particularly important in applications where electrical devices are in close contact with patients, as continuous DC exposure can cause unintended stimulation of nerves and muscles.

In contrast, alternating current (AC) is more commonly used in medical devices because it alternates direction, reducing the risk of maintaining a continuous contraction in muscles. Other forms of current, like battery current or specific pulsing patterns, can be managed to ensure safety and efficacy in medical settings, while moisture current does not represent a standard electrical current type relevant to safety concerns in biomedical applications.
