How do biological tissues behave with electrical signals?

Biological tissues exhibit unique properties when it comes to electrical signals. Their behavior is characterized by both resistive and capacitive properties, which are crucial for understanding how they interact with current. The resistive aspect relates to how tissues oppose the flow of electric current, with resistance levels varying among different types of tissues. The capacitive aspect involves the ability of tissues to store electrical energy temporarily.

This dual nature plays a vital role in various applications, including medical imaging and therapies using electrical signals. For example, when electrodes are applied to the skin, the electrical signals can propagate through the resistive and capacitive components of the tissues, influencing diagnostic assessments and therapies. Recognizing that biological tissues do not simply block or convert electrical signals but instead manage them through resistive and capacitive interactions is essential in fields such as bioengineering and medical technology.
