Wearable architecture and methods for performance monitoring, analysis, and feedback
The present application relates generally to computer software, mobile electronics, wireless communication links, and wearable monitoring systems. More specifically, techniques, fabrics, materials, systems, sensors, EMG sensors, circuitry, algorithms and methods for wearable monitoring devices and associated exercise apparatus are described. A garment borne sensor system may generate data on a user's performance during exercise, for example, and the data may be analyzed in real time and feedback may be provided to the user based on the analysis. A piece of exercise equipment may be instrumented and in communication with the sensor system or other system and may be controlled in real time to adjust its settings to affect the user during the exercise routine. Communication between the sensor system and other systems may be wireless. Conductive structures formed directly in a fabric of the garment may integrally include sensors, circuitry, controllers, conductive traces, and sensor electronics.
