bioelectricity
Living tissue voltage
Bioelectricity is the electrical activity generated by living organisms.
Nerve impulses, heartbeats, and muscle contractions all involve bioelectric signals—the flow of ions across cell membranes creating measurable voltages.
Medical devices like EKGs and EEGs detect bioelectricity to monitor heart and brain function.
Some animals, like electric eels, produce bioelectricity powerful enough to stun prey.
