摘要： Embodiments are directed to a pressure mapping system that includes a sensing pad configured for placement between a user and a bed. The sensing pad can include an array of actuation cells where each actuation cell in the array of actuation cells is configured to actuate in response to a fluid being introduced into the actuation cell. The sensing pad can also include an array of pressure sensors where each pressure sensor in the array of pressure sensors is configured to output pressure measurements. The pressure mapping system can also include a control system that is configured to receive the pressure measurements from the array of pressure sensors, generate a pressure map for the user based on the set of pressure measurements and a position of the pressure sensing cells on the sensing pad, and actuate a subset of the array of actuation cells based on the pressure map.
