Application And Direction Of Smart Sensors

Smart sensors have been widely used in various fields such as aerospace, aviation, national defense, science and technology, and industrial and agricultural production. For example, it has broad application prospects in the field of robotics. Smart sensors enable robots to have human-like facial features and brain functions, which can perceive various phenomena and complete various actions.

In industrial production, some product quality indicators (such as viscosity, hardness, surface finish, composition, color, and taste, etc.) cannot be quickly and directly measured and controlled online using traditional sensors. The use of smart sensors can directly measure certain quantities in the production process (such as temperature, pressure, flow, etc.) that are functionally related to product quality indicators. Use the mathematical model established by neural network or expert system technology to calculate, and infer the product the quality of.

In the medical field, diabetic patients need to keep track of their blood sugar levels in order to adjust their diet and inject insulin to prevent other complications. Usually when measuring blood sugar, you must pierce your finger to collect blood, then put the blood sample on the glucose test paper, and finally put the test paper on the electronic blood glucose meter for measurement. This is a troublesome and painful method. And "glucose watch", its appearance is like ordinary watch, wearing it can realize painless, bloodless, continuous blood sugar test. There is a cushion coated with reagents on the "glucose watch". When the cushion is in contact with the skin, glucose molecules are adsorbed on the cushion and electrochemically react with the reagents to generate an electric current. The sensor measures the current, the processor calculates the blood glucose concentration corresponding to the current, and displays it as a digital quantity.
