Abstract
Abstract: Lymphedema is a phenomenon in which fluid is accumulated inside tissues due to the damaged lymphaticsystems. Lymphedema can cause complications such as lymphangitis, infection, changes in skin texture, fibrosis, andlymphangiosarcoma. In this study, a lymphedema screening system based on the elasticity of the skin is proposedto easily quantify lymphedema. The developed probe consists of touch sensors, a load cell and hall-effect sensorsto measure the indentation force on the skin and the return time of the skin. The developed system can be usedto estimate the change in the elasticity of the skin to quantify lymphedema. The system was tested with a thyroidphantom and gelatin phantoms of different concentrations and the resulting force and the time were recorded. It wasfound that the increase in the elasticity leads to a higher indentation force and shorter return time. This shows thatthe developed system can monitor the change in the skin elasticity by measuring the return time and the indentationforce. The feasibility of the system in clinical applications will be evaluated in the future study.Key words: edema, lymphedema, skin elasticity, lymphedema screening, lymphedema examination
