Onboard Storage

Biosensor data stream should be stored in a non-volitile manner on the data aggregator board attached to the body. Ideally, the biosensor array will stream data wirelessly to a smart phone or computer, but this should not be required to ensure operational flexibility. Therefore, a moderate amount of on board storage is required.
