Abstract

A system for biometric monitoring may include a patch, a plurality of electrodes, a flexible printed circuit, and a cradle. The patch may be adapted to adhere to a patient's skin. The plurality of electrodes may be carried by the patch. The flexible printed circuit may be carried by the patch and include an electrical pad and a trace adapted to provide electrical communication between the plurality of electrodes and the electrical pads. The cradle may be affixed to the patch. A back side of the flexible printed circuit directly opposing the electrical pad may be affixed to the front surface of the cradle. The electrical pad may be adapted to electrically engage an electrical contact located on a biometric monitoring device carried by the cradle.
