Patients who are bound to a wheelchair or bed, especially those with spinal cord injuries, often suffer from decubitus ulcers or pressure sores with great detrimental effects to their quality of life and productivity. This subset of people is most affected by pressure sores, up to 85% of these patients suffer from decubitus ulcers at least once in their lifetime, because due to their spinal cord injuries they lack feedback from their bodies regarding pain and do not perform sufficient pressure relief movements. An interesting option to provide an improvement to their care is an intelligent seat cushion, which is capable of measuring the pressure distribution and then use this information to perform some form of pressure relief. Such a functionality can be provided by electroactive polymer actuators. In this thesis the feasibility of using electroactive polymer actuators in a seat cushion is evaluated.
