Abstract

A wearable diagnostic device worn on a user's body that can provide various types of health-related information to the user is described. The wearable diagnostic device can provide real-time, non-invasive, accurate, and continuous data regarding a user's heart rate, hemoglobin level, body temperature, oxygen level, glucose level, and blood pressure. In some implementations, the wearable diagnostic device may also provide electrocardiogram (EKG) data or detection of Parkinson's symptoms, such as the involuntary movement of a user's hand. A user may configure the wearable diagnostic device to provide information on one, multiple, or all of the health-related information noted above.
