A “smart bandage” or “smart patch” incorporates neither elastic bands nor wired individual sensors into its construction for physiological monitoring, especially heart rate sensing methods. The patch has an electronic circuit and battery, sandwiched between layers of insulating material and cover plastics. On the skin contacting side of the assembly, a pair of conductive, adhesive gel pads are intended to be placed upon the torso or abdominal area of a human or other mammal in order to sense the heart-rate voltage differential across the sensors. The signals are amplified and filtered by the internal electronics. A microcontroller then converts the heart-rate data information into one of multiple data output formats, which are sent by radio data transmission to any variety of outside receiving equipment. |
