The SENSIMAT for Wheelchairs is a thin, wireless mat of pressure sensors that is inserted underneath a wheelchair cushion. The mat connects via Bluetooth to the SENSIMAT mobile app which allows 24/7 monitoring of the wheelchair cushion.
The SENSIMAT is fully customized to your wheelchair cushion(ie. 16 inches front to back, 18 inches left to right). The SENSIMAT is inserted directly underneath your wheelchair cushion and zipped up in the existing wheelchair cushion sleeve.
The SENSIMAT is comprised of the sensor hardware, the SENSIMAT mobile app, and the SENSIMAT web portal. The hardware is 1/2 an inch thick with strategically-placed force sensors contained by a medical-grade fabric. The hardware has an on/off switch and a micro-USB charging port, but is otherwise wireless.
The SENSIMAT sends the pressure data to a mobile app via Bluetooth. A proprietary algorithm on the app detects whether a wheelchair user is: in/out of the seat, leaning left, right, forward, or is lifting off the seat. As the user is seated, visual indicators will turn from green to yellow and then red after the user-adjusted time has elapsed (ie. 15/30 minutes). User managed alerts (ie. vibrate, ring) are provided at each change. If a relief movement is detected, the sensor colors are reset to green and the relief type is logged in the dashboard. The mobile app syncs with our server, where we store 3.6 million data points/user/week. SENSIMAT data can be accessed through the mobile app dashboard, or through the web portal.
