Abstract: Electrode systems for use with neuromuscular monitoring systems are provided herein. An example electrode system for use with a monitoring system can include a flexible substrate, a connector interface, one or more stimulating electrodes, one or more recording electrodes and a plurality of conductive traces carried on the flexible substrate. The connector interface can be configured to communicatively connect the electrode system with the monitoring system. In addition, the one or more stimulating electrodes can be configured to deliver an electrical pulse, and the one or more recording electrodes can be configured to receive an electrical signal. The plurality of conductive traces can electrically connect at least one stimulating electrode or at least one recording electrode with the connector interface. Further, each of the one or more stimulating electrodes can have an elongate shape with a length dimension that is substantially greater than a width dimension.

Abstract: A system for determining the hydration status of an individual utilizes a light sources and a photodetectors to extract a plethysmographic waveform from an individual and applies feature extraction to extract features from said plethysmographic waveform from which the hydration status of the individual can be inferred or calculated. The system of preferably housed in a wearable housing.
