This golden donut is likely a streamlined antenna, as we've not seen the fiddly brackets or golden gaskets of yesteryear. Meanwhile, we've come to the headline feature: new electrical heart sensors (ECG) to complement existing optical sensors. The Apple Watch is a Lead I ECG, which means it's only measuring voltage between the right and left arms. The first electrode is on the Watch back, pressed against your wrist. The second is the crown, held by your opposite hand's fingers.

  • Meanwhile, we've come to the headline feature: new electrical heart sensors (ECG) to complement existing optical sensors.

  • The Apple Watch is a Lead I ECG, which means it's only measuring voltage between the right and left arms. The first electrode is on the Watch back, pressed against your wrist. The second is the crown, held by your opposite hand's fingers.

  • These electrodes detect tiny changes in electrical polarization across your skin as your heart beats. The S4 then interprets that data to compute and analyze your heart rhythm.

Este donut dorado es probablemente una antena aerodinámica, ya que no hemos visto los soportes complejos o las juntas doradas de antaño.

Mientras tanto, hemos llegado a la característica principal: nuevos sensores eléctricos del corazón (ECG) para complementar los sensores ópticos existentes.

El Apple Watch es un ECG de Derivación I , lo que significa que solo mide el voltaje entre los brazos derecho e izquierdo. El primer electrodo está en el reloj, presionado contra su muñeca. El segundo es la corona, sostenida por los dedos de la mano opuesta.

Estos electrodos detectan pequeños cambios en la polarización eléctrica a través de su piel a medida que tu corazón late. El S4 luego interpreta esa información para calcular y analizar tu ritmo cardíaco.
