Abstract

A health-monitor patch comprising at least one physiological sensor and digital processor is configured to be adhered to the skin of a subject. A health-monitor patch may further include an accelerometer and may detect cardiac waveforms, activity performed by the subject, and a body orientation of the subject. A health-monitor patch may be disposable, in some embodiments, and used for outpatient monitoring. Aspects of noise cancellation and reel-to-reel manufacturing are also described.

Claims

1. A method for forming a component of a wearable monitor for a subject, comprising:

using a first roll of material, forming a first component layer that incorporates a first circuit component;

using a second roll of material, forming a second component layer that incorporates a second circuit component;

adhering a flexible, conductive adhesive film to the first circuit component; and

electrically connecting the first circuit component to the second circuit component via the flexible, conductive adhesive film disposed between the first and second component layers so as to establish a conductive path for carrying a signal indicative of a monitored characteristic of the subject between the first circuit component and the second circuit component of the wearable monitor via the flexible, conductive adhesive film.
