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.
