Ecg Heart
How does the censors that capture the heart electrical activity on a ECG work?
I mean how can it capture electrical activity by resting on the surface of the skin?
The sensors are inert metal electrodes, placed on the skin in the vicinity of the heart. Usually there will be a reference (earth) electrode on the ankle. What is being measured and displayed is the varying voltage generated by the action of the heart muscle. In magnitude it is about 1 mV so it needs to be amplified before display.

Heart of Saturday Night [Vinyl] $19.86 The Eagles might have covered his song “Ol’ 55,” but Tom Waits was cut from a different cloth than California’s other singer-songwriters–he suggested a scruffy beat poet who’d walked out of a forgotten scene of Jack Kerouac’s On the Road.
