Fabrication and Testing of an Osmotic Pressure Sensor for Glucose Sensing Application
This paper presents a chemical reaction-free sensor, based on the osmosis principle, fabricated to measure the change in glucose concentration levels. The sensor consists of a square cavity filled with a known concentration of glucose solution and sealed with a semi-permeable membrane. The volume in...
