Systems and methods are provided for wirelessly obtaining a physiological signal from a patient. In one embodiment, a system comprises a plurality of sensors spaced apart from one another and adapted to measure physiological signals from a patient, and a communication module configured to wirelessly transmit the physiological signals measured by the plurality of sensors to a computing device. In this way, a fabric cover with the plurality of sensors and the communication module integrated therein may be washable and/or disposable while also enabling acquisition of an ECG signal and/or heart rate for neonatal or infant care applications.

Systems and methods for wirelessly obtaining a physiological signal from a patient

A method of sensing the heart rate and blood oxygen saturation of a maternal patient and a fetal patient can include obtaining maternal electrocardiogram (mECG) data and fetal electrocardiogram (fECG) data with a plurality of electrodes. The method can also include obtaining photosignal data with an optical sensor, the photosignal data including a maternal photosignal component and a fetal photosignal component. Additionally, the method can include applying mECG to the photosignal data to calculate maternal photoplesthograph (mPPG) data, applying the mPPG to the photosignal data to remove the maternal photosignal component from the photosignal data, and applying the fECG to remaining photosignal data to calculate fetal photoplesthograph (fPPG) data.

Multi-sensor patch

Various methods and systems are provided for a fabric cover including a plurality of integrated electrodes for measuring an electrocardiogram signal of a patient in direct contact with at least a subset of the plurality of integrate electrodes. As one example, a fabric cover for an infant incubator or warmer includes a plurality of electrodes spaced apart from one another within a measurement area of a surface of the fabric cover adapted to have direct contact with a patient, the plurality of electrodes including a topmost electrode extending across an entire width of the measurement area, a bottommost electrode extending across the entire width of the measurement area, and a set of electrodes arranged between the topmost electrode and bottommost electrode, in a direction perpendicular to the width, within the measurement area.

Various methods and systems are provided for selecting sensors for acquiring physiological data of a patient. In one embodiment, a system comprises a plurality of sensors, a dynamic selection switch communicatively coupled to the plurality of sensors, a plurality of acquisition channels communicatively coupled to the dynamic selection switch, and a processor communicatively coupled to the dynamic selection switch and configured with executable instructions in non-transitory memory that when executed cause the processor to: select a subset of sensors; control the dynamic selection switch to connect the subset of sensors to the plurality of acquisition channels; and acquire, from the subset of sensors via the plurality of acquisition channels, physiological data of a patient. In this way, a subset of sensors in a plurality of sensors may be dynamically selected in real-time for acquiring physiological data of the patient.

A multi-sensor patch for simultaneous abdominal monitoring of maternal and fetal physiological data includes a multi-layer flexible substrate. The multi-layer flexible substrate includes a center region and a plurality of electrode regions. An electrode of the plurality of electrodes is located in each of the electrode regions. At least one auxiliary sensor which may be an optical sensor. A module unit is connected to the conductive layer at the center region. The module unit is configured to receive biopotential physiological data from the plurality of electrodes and photosignal data from the optical sensor. The module unit calculates at least fetal heart rate (fHR), maternal heart rate (mHR), and uterine activity (UA) from the biopotential physiological data and fHR, mHR, and SpO2 from the photosignal data.

Various methods and systems are provided for a drift-compensated force measurement. In one example, a method includes obtaining a single output voltage measurement from a strain gauge of an infant scale, the single output voltage reflective of a weight applied to the scale; obtaining a voltage measurement across each of four resistors of the strain gauge to determine four separate voltage measurements and determining a drift voltage based on the four separate voltage measurements; and outputting a corrected weight value determined based on a difference between the single output voltage and the drift voltage
