Wrist-Mounted Electrocardiography Device

摘要

Wearable devices are described herein including a housing and a mount configured to mount the housing to a wrist of a wearer. The wearable devices further include first and second electrical contacts configured such that the first electrical contact is in contact with skin proximate of the wrist when the wearable device is so mounted. The second electrical contact is disposed on a surface of the wearable device away from the wrist such that, when the wearer contacts the second electrical contact with a finger or other element of the arm opposite the wrist, an electrocardiographic waveform of the wearer can be extracted from voltage fluctuations between the first and second electrodes. Such wearable devices can be used for periodic logging or other applications of the electrocardiographic waveforms of the wearer. Such logged electrocardiographic waveforms could be used to determine a medical or health state of the wearer.

主权项

1. A wearable device, comprising:
a housing; a mount configured to mount the housing to a first external body surface, wherein the first external body surface is a wrist location of a first arm of a wearer; a first electrical contact disposed on the housing, wherein the first electrical contact is configured to contact skin at the first external body surface when the housing is mounted on the first external body surface; a second electrical contact, wherein the second electrical contact is configured to be contacted by skin of a second external body surface, wherein the second external body surface is a location of a second arm of the wearer; and a signal conditioner disposed in the housing and electrically connected to the first and second electrical contacts, wherein the signal conditioner is configured to extract an electrocardiographic waveform from voltage fluctuations between the first electrical contact and the second electrical contact.
