For the study, Dunn's team gave 31 volunteers a nasal dose of H1N1 flu and 18 a common cold virus. Participants wore the sensor wristband for four days before and five days after inoculation.

Using only data from the wearable devices, the researchers could tell the difference between those infected and those not infected with up to 92% accuracy for H1N1 and 88% for the cold virus. The data could also distinguish between mild and moderate infection a day before symptoms started with 90% accuracy for H1N1 and 89% for the cold virus.
