Wearable sensors have the potential to enable continuous real-time health monitoring of people during normal daily activities. In contrast, the current paradigm requires patients to devote a period of time to attend for tests in specialist facilities and under conditions that, at best, are not representative of their normal life patterns, and at worst, may induce considerable stress, leading to significantly biased data. Physical therapy, training technique, rehabilitation, respiration monitoring and diagnostics could all be improved by implementing wearable sensors and data acquisition software. This will not only improve the accuracy of the measurements, but the ability to analyze the data over time.
