Abstract
A method is disclosed for foot sensors to be used to determine at least two characteristics of a subject's activity by using a combination of sensors for force and foot orientation/motion/position. A wearable footwear ecosystem is comprised of the subject's footwear, sensor-enabled insoles or insertable devices, in- or on-footwear electronics that is hard wired to the sensors and may contain additional sensors such as accelerometers, a master device and means to communicate (typically wirelessly) among the various sensor platforms, and the master device including clock synchronization. Correlating the time stamps for data among various sensors, and the master device communicating wirelessly is critical to accurate determination of the desired characteristics. Multiple force-sensitive resistors on a common substrate are individually optimized for dynamic range. Pulse sensors using arrays of such force-sensitive resistors are implemented. The resultant system can profitably be used for gaming, biometric monitoring, and activity tracking.
