1. Pressure Ulcer Reducing Pad : Under Pressure Pad

Objective: Create a device that can be used as a chair cushion to prevent pressure ulcer formation, and provide the patient with a solution that allows them to operate the device independently.
Approach: Use inflating bladders to help redistribute pressure and tilt the patient 15 degrees in order to help blood circulation and oxygen levels in the injury site to improve. Also, use force sensors in order to prevent any dangerous amount of pressure on any one point.
Impact: Keep patients out of the hospital by using this wheelchair pad that is comfortable, independent, and properly manages the risk factors associated with pressure ulcers.
Progress and Results:
8 air bladders fabricated to withstand 375 pounds
Calibration and implementation of force sensors
Arduino code that operates automatically and has overrides for sensor data or user input
15 degree of tilt achieved by inflatable bladders
Outer material can withstand puncture and water
Pressure Alternating
Tilt Phase
