Vibe : Low-Power Wireless Body Motion Sensor

1. Vibe : Low-Power Wireless Body Motion Sensor Team Members: Corey Provencher, Adam Spirer Body Area Sensor Network What is Vibe? • Vibe is a low-power, wireless body motion sensing platform. • Vibe can network with up to 5 additional devices to create a wireless Body Area Sensor Network. • Vibe has a 6-axis IMU for advanced motion tracking. • Internal extended storage allows Vibe to log motion data for analysis by physicians, researchers. • Rechargeable battery with >1 week battery life for a typical application.* Motivation • Mother of a child with chronic epilepsy was required to sleep in close proximity of her son to medicate before onset of a seizure. • Envisioned Vibe as a body tremor sensor to detect onset of seizures and alert caretaker. • Development and deployment to researchers of a wireless body motion sensor with a rich and easy to use API. • No current product on the market that has the feature set of Vibe.
