Abstract: Cardiac monitor devices are described. An exemplary cardiac monitor device can take the form of an armband that can be worn by a user. The cardiac monitor device can be paired with an electronic device so that the user can access information of his or her heart activity. In one embodiment, the cardiac monitor device can include a body that can be worn at a limb of the user. The body can carry different electronic components. The electronic components can include an electrode configured to come into contact with a location of the limb and configured to measure a first electrical potential at the location. The electronic components can also include an antenna configured to capacitively couple with the body of the user to generate a second electrical potential. The electronic components can further include an amplifier configured to amplify the potential difference.
