A ballistocardiography device comprises: a support for a person, a plurality of pressure or acceleration sensors each providing an analogue signal representative of a pressure or an acceleration measured at a point on the support or on the body of the person, a multiplexer (41) configured to receive a plurality of analogue signals from sensors and to output a signal successively representative of the input signals and an operational amplifier (52) having one input (57) connected to the output of the multiplexer and provided, on its other input, with a mixed filter comprising an analogue-to-digital converter (53) converting the signal coming out of the multiplexer into digital data, a digital filter (54) acting on the digital data and a digital-to-analogue converter (55) converting the filtered digital data into an analogue signal that is fed into the other input (58) of the operational amplifier.

Various examples are provided for non-contact vital sign acquisition. Information can be provided regarding vibrations of a target using a radar signal such as, e.g., non-contact vital sign measurement. Examples include estimation of heart rate, change in heart rate, respiration rate, and/or change in respiration rate, for a human or other animal. Implementations can produce one or both rates of vibration and/or change in one or both rates of vibration for a target other than an animal or human experiencing two vibrations at the same time, such as a motor, a vehicle incorporating a motor, or another physical object. Some implementations can estimate the respiration movement in the radar baseband output signal. The estimated respiration signal can then be subtracted from radar signals in the time domain and, optionally, can be further enhanced using digital signal processing techniques, to produce an estimate of the heartbeat pulses.

In some examples, a system may be used for delivering cardiac therapy or cardiac sensing. The system may include an in implantable medical device including a housing configured to be implanted on or within a heart of a patient, a fixation element configured to attach the housing to the heart; and a sensor configured to produce a signal that indicates motion of the implantable medical device. Processing circuitry may be configured to identify one or more impingements between the housing and another structure, such as a tissue of the heart, based on the signal from the sensor and provide an indication of the one or more impingements to a user.

A sensor network for pregnancy monitoring of a subject includes a plurality of sensor systems time-synchronized to each other, each sensor system placed on a respective region of the subject and having a sensor member configured to detect data associated with at least one of physiological parameters of the subject, and a Bluetooth low energy system-on-a-chip configured to process and transmit the detected data; and a controller adapted in wireless communication with the plurality of sensor systems and configured to receive, from the plurality of sensor systems, to process, and to display the physiological parameters.

A conformal patch device can be provided to a patient. The patch device can include sensors configured to be positioned over a chest of a patient. The sensors can include PPG sensors, ECG sensors, and SCG sensors. The conformal patch device can to adhere to a single continuous area of the chest. Some sensors may attached to a viscoelastic substrate to achieve mechanical isolation from other patch components. The conformal patch device can capture measurements from the sensor doing a time window sufficient enough to detect disordered breathing. The system can determine disordered breathing and related cardiorespiratory parameters during the time window for the patient using the sensor measurements.

The present disclosure relates to a coil assembly of an MRI device. The MRI device may be configured to perform an MR scan on a subject. The coil assembly may include one or more coil units, a substrate, and a sensor mounted within or on the substrate. The one or more coil units may be configured to receive an MR signal from the subject during the MR scan. The substrate may be configured to position the one or more coil units during the MR scan. The one or more coil units may be mounted within or on the substrate. The sensor may be configured to detect a motion signal relating to a physiological motion of the subject before or during the MR scan.

A method for generating electrocardiogram (ECG) signals includes detecting at least one cardiac motion induced signal. The at least one cardiac motion induced signal is a seismocardiography (SCG) signal. The method includes transforming the at least one detected cardiac motion induced signal into at least one ECG signal. Multiple channel-specific signals of a multi-channel ECG signal are determined by the transformation from the at least one SCG signal.

An acquisition apparatus for acquiring physiological data of an individual, configured to be installed in a bed frame, with an acquisition portion which includes a sensor intended to capture mechanical waves transiting in the bed frame, a support device including one or more rigid panels, the support device being configured to rest on bed frame elements which may be discontinuous for example slats, so that the support device is interposed between the bed frame elements and the sensor, and may provide a substantially continuous support to the sensor receiving the mechanical waves generated by the individual through the bedding, if necessary with folding zones between panels.

Provided is a contactless electrocardiogram measurement device which may perform a high-quality sleep monitoring while improving a sleep quality of an object person. The contactless electrocardiogram measurement device includes a measurement unit disposed between a vibration medium and a support member to measure vibration generated from a body of an object person that is transmitted from the vibration medium, wherein the measurement unit includes a plate-shaped cover portion interposed between the vibration medium and the support member, and a vibration sensor for detecting the vibration generated in the cover portion.

A garment for detecting physiological data. The garment may include a garment body and a primary sensor panel affixed to a user facing side of the garment body. The primary sensor panel may include at least one bio signal sensor type to generate a primary set of bio signals. The garment may include a processor coupled to the primary sensor panel and a memory coupled to the processor. The memory may store processor-executable instructions that, when executed, configure the processor to: receive, from the primary sensor panel, the primary set of bio signals; generate a bio signal waveform based on the primary set of bio signals; and determine a hemodynamic metric associated with the user based on the bio signal waveforms associated with the user.
