An ECG sensor system comprising: a substrate having a first side and a second side, the substrate of a non-conducting material; a plurality of textile-based sensors positioned on the first side, each of the plurality of textile-based sensors spaced apart from one another on the first side, the second side covering one side of the each of the plurality of textile-based sensors as an insulating covering, the each of the plurality of textile-based sensors including conductive fibres interlaced with one another; and a conductive trace connected to the each of the plurality of textile-based sensors, each of the conductive traces for connecting the plurality of textile-based sensors to an electronic controller for sending and receiving electronic signals from a selected pair of the plurality of textile-based sensors.

A cardiac monitoring system that automatically determines whether one or more electrodes are placed at wrong positions on a person's body includes an ECG monitor. The electrodes are connected to the ECG monitor wirelessly or by wire. Each electrode includes a position code that corresponds to a body location where the electrode is to be placed. The signals that are transmitted from each electrode include the position code assigned to the electrode. The profile of the signals received from the electrodes are compared with expected profile of the signals from the electrodes that are placed at each specific position on the body. The position code in the transmitted data of any electrode that is determined to be placed at a wrong position is automatically replaced with the position code corresponding to the electrodes' actual position. The leads are then determined based on the electrode signals and the electrodes' position codes.

Adaptive biosignal systems and methods are disclosed for switching one or more designations of biosignal sensors for dynamic adaptation and optimization of one or more biosignal detection devices. A sensor designation cycle is executed for a plurality of biosignal sensors of a biosignal detection device, each of the plurality of biosignal sensors configured to collect biosignal data of a user, and each of the plurality of biosignal sensors having a designation defining an electrical sensor modality modifiable by a switch communicatively coupled to the biosignal detection device. The plurality of biosignal sensors comprises at least a first biosignal sensor, a second biosignal sensor, and a third biosignal sensor, wherein the first biosignal sensor is designated as a reference sensor, and wherein the second biosignal sensor is designated as a measurement sensor. The sensor designation cycle comprises various algorithms for switching designations of the various sensors.

Detecting user contact with one or more electrodes of a physiological signal sensor can be used to ensure physiological signals measured by the physiological signal sensor meet waveform characteristics (e.g., of a clinically accurate physiological signal). In some examples, a mobile and/or wearable device can comprise sensing circuitry, stimulation circuitry, and processing circuitry. The stimulation circuit can drive one or more stimulation signals on one or more electrodes, the resulting signal(s) can be measured (e.g., by the sensing circuitry), and the processing circuitry can determine whether a user is in contact with the electrode(s). Additionally or alternatively, in some examples, mobile and/or wearable device can comprise saturation detection circuitry, and the processing circuitry can determine whether the sensing circuitry is saturated.

An electrode arrangement measures electric voltages and currents in the human body and provides electro-simulation of the human body. The electrode arrangement contains an electrode array with a flexible support. A number of electrodes are arranged in a grid on the same side of the support and slots are disposed between the individual electrodes starting from the outer edge of the support. An elastic intermediate layer that has one recess for each electrode is provided, each recess defining a cavity to be filled with an electrically conductive gel.
