bioelectric
Living tissue's electricity
Bioelectric describes electrical phenomena produced by or occurring in living organisms.
The human body generates bioelectric signals through nerve impulses, muscle contractions, and brain activity, all of which can be measured by instruments like EKGs and EEGs.
Bioelectric signals from the heart can reveal underlying cardiac conditions.
The term appears frequently in medical and biological contexts, often paired with words like current, potential, or field.
