The invention provides a low cost, fully integrated, disposable patch for the non-invasive monitoring of labor contractions. The patch monitors EMG bursts present on a pregnant woman's abdomen via a set of electrodes embedded in the invented patch. The contraction monitor patch is thin, flexible, and incorporates EMG amplifiers, a processor, a battery, and an indicator within. The indicator is activated when labor EMG patterns are detected. The labor detection patch is particularly suited for women with risk of premature delivery. The patch is unobtrusively and continuously worn, even during sleep and bathing. In another embodiment, the contraction monitor patch is used in hospitals during labor and delivery to monitor the status of contractions with a wireless link to an external monitoring unit.
