My idea of a new wearable technology would be to have a bracelet or some other similar accessory that would be able to detect illness before it happened. You could simply breathe your germs all over the device in order for it to pick up dangerous germs. As it detected the beginning of the cold, flu, etc, it would alert the wearer and send a health recommendation or prescription (if needed) to the wearer’s email. Ideally it would be able to detect the beginning stages of more serious illnesses- cancer, diabetes, etc. so that the wearer could take action immediately.
The detection of more serious illnesses would be a challenge…any illness that requires drawn blood could become a problem. Perhaps it could act similar to a diabetes blood monitoring system?
