Research Abstract
The ultimate goal of the project was to establish the basis for the introduction of sonography into the international diagnostic criteria for Sjogren's syndrome. We tried to achieve quantification/objectivity of the diagnosis through the application of ultrasound elastography. Elastography images and measurements are affected by the pressure applied. In this study, to keep the pressure applied during examinations within a certain range, we attempted to develop a pressure sensor that can be attached to the probe. Elastic springs, slide resistors, and stainless steel movable plates were connected to a support surface. When the movable plate is moved, the spring extends and the resistance value increases. The amount of change was measured as a voltage by applying a constant voltage to the entire area. The force applied and the display on the digital panel were in a linear relationship. Therefore, the prototype of pressure sensor could be successfully developed.
