Patently Apple reports that Apple has applied for a patent related to a wearable electrocardiographic (ECG) device that could take the form of a watch, ring, brooch or similar.
A wearable device can be affixed to a limb of the human body such as a wrist or ankle, as an example. The wearable device can be worn on the left or right wrist, or even on the right or left ankle.
