The present invention relates to a non-invasive cardiac monitoring device that records cardiac data to infer physiological characteristics of a human, such as cardiac arrhythmia. Some embodiments of the invention allow for long-term monitoring of physiological signals. Further embodiments allow for processing of the detected cardiac rhythm signals partially on the wearable cardiac monitor device, and partially on a remote computing system. Some embodiments include a wearable cardiac monitor device for long-term adhesion to a mammal for prolonged detection of cardiac rhythm signals.

In electrocardiography (ECG) system, a patient cable connecting one or more electrodes to a processing device for processing ECG signals may include one or more electrode connectors mechanically keyed to respective electrodes and/or a device connector mechanically and/or electronically keyed to a cable connector of the processing device. In some embodiments, keying between the cable and electrode is achieved, for example, with an electrode including a hollow-post portion that defines a bore in conjunction with a post protruding from an arm of the electrode connector that is sized to fit within the bore.

Disclosed are a method and system for monitoring movement. The system includes: a muscle movement sensor, a movement capturing device and a processing device, wherein the muscle movement sensor is configured to acquire muscle movement information of a moving part of a living body in the case that the muscle movement sensor is fixed onto the moving part; the movement capturing device is configured to acquire whole movement information of the living body; and the processing device is configured to determine a movement parameter of a muscle of the moving part based on the muscle movement information and the whole movement information.

This invention is a dry EEG electrode with an articulated distal base and/or a plurality of articulated conductive proximal protrusions which penetrate between strands of hair for good electromagnetic contact without causing discomfort or skin irritation.

A wearable monitoring device can include an electronics module containing a printed circuit board (PCB) to which one or more sensors are coupled. The one or more sensors can include one or more contacting sensors and/or one or more non-contacting sensors. In some cases, the wearable monitoring device can include an onboard power supply (e.g., a battery) and a wireless communication antenna. The PCB can be constructed to specifically include the one or more sensors on a first side facing the skin of the user when the wearable monitoring device is being worn, allowing one or more processors, memory, and other components to be included on the opposite side facing away from the user. Certain components, such as the power supply and wireless communication antenna, can be spaced apart from the PCB and located opposite the PCB from the one or more sensors.

An on-body sensor unit (12) comprises a PPG sensor and an ECG sensor, each having sensor parts exposed at a skin-contacting surface (16) of the unit. The PPG includes an optical detector (22) and at least one light source (20a, 20b). Disposed between the at least one light source and the optical detector is a light-intercepting surface element (28), adapted to be absorptive of light of at least a majority of a spectral composition which is generated by the at least one PPG light source (20a, 20b). Located within, or forming, this surface element is an electrode (32a, 32b) comprised by the ECG sensor, said electrode having at least an exposed skin-interfacing surface which is absorptive of a majority of the spectral composition of said light generated by the at least one light source.

Some embodiments include processing data via an executable file on a monitor to reduce the dimensionality of the data being transmitted over the wireless network. The output of the executable file also encrypts the data before being transmitted wireless to a remote server. The remote server receives the transmitted data and makes likelihood inferences based on the recorded data.
