McNeill, John A.
There is a need for a device that can detect the early presence of pressure ulcers in order to reduce the costs and time spent on taking care of patients that are at high risk for pressure ulcer development. This MQP describes a pressure ulcer detection device that is based on the use of bioimpedance. In order to test the efficacy of the device, a tissue phantom material was needed to reduce testing costs and optimize specific device parameters. In order to accomplish this task, phantom materials were investigated and tested to determine which material would be able to replicate the electrical response of human skin across a wide range of frequencies. Potatoes were able to replicate a similar bioimpedance response to that of humans and were modified to simulate a pressure ulcer.
