The SensiMAT for Wheelchairs is the first and only mobile medical application that help users track, relieve, and analyze pressure and pressure trends. The SensiMAT for Wheelchairs is a thin mat containing pressure sensors that is inserted underneath your gel, air, or foam cushion. These sensors send pressure data to a mobile device, where SensiMAT Systems’ proprietary PressureRisk™ algorithm alerts the user when they have a high amount of built up pressure, and facilitates and tracks pressure relieving exercises. The SensiMAT can be thought of as an analog to many consumer-based “Quantified Self” devices (like Fitbit, Nike Fuel Band, BodyMedia, Jawbone UP, etc.) with the main measurable objective being that of seat pressure and user activity, providing SensiMAT with a “Quantified Seat”.
