A system for achieving optimal sensor placement and enhanced signal quality for monitoring maternal and fetal activities is disclosed. The system includes a monitoring device and a computing unit. The monitoring device is configured for monitoring maternal and fetal activities and providing guidance to the user via the computing unit upon detecting a feature of interest. The monitoring device includes a plurality of sensors, a data acquisition and transmission unit, one or more reference electrodes, and a ground electrode. Based on personal data acquired using the computing unit, the system utilizes a statistical or machine learning model which incorporates one or more subsets of the personal data to determine the optimal sensor placement close to the fetal heart position. Following sensor placement, the monitoring device performs a signal quality assessment and selects the optimal sensors to ensure reliable information on maternal and fetal activities is obtained.

A method of determining and treating disordered tissue in a patient incites energy signal generation from disordered tissue. An energy sensor structure obtains an energy signal from tissue of a patient. The obtained energy signal is compared in a processor circuit to a known energy signal of the same tissue under normal functioning of the tissue. The tissue is identified as disordered tissue when the comparing step determines that the obtained energy signal is different from the known energy signal. The disordered tissue is localized within the patient via the energy signal. A bodily disorder caused by the localized disordered tissue is diagnosed by an AI module. The bodily disorder is then treated.
