What are Active Feedback Systems?
Active feedback systems are control mechanisms that use real-time data to adjust the performance and behavior of a system automatically. In the context of
nanotechnology, these systems are crucial for achieving precise control over nanoscale processes and devices.
How do Active Feedback Systems Work in Nanotechnology?
In nanotechnology,
active feedback systems typically involve sensors, actuators, and controllers. Sensors collect data on various parameters such as temperature, pressure, and chemical composition. This data is then processed by controllers, which send signals to actuators to make real-time adjustments. For example, in
nanofabrication, these systems can regulate conditions to ensure consistent quality and performance.
