Sensor performance refers to the ability of a sensor to accurately and reliably measure the physical quantities it is designed to detect. This includes factors such as accuracy, precision, sensitivity, resolution, response time, and stability. High sensor performance is essential in many applications, such as industrial process control, medical diagnostics, environmental monitoring, and consumer electronics. Researchers in this area aim to improve sensor performance through advancements in sensor design, materials, signal processing algorithms, and calibration techniques. They also work to optimize sensor performance in specific operating conditions and environments to ensure accurate and reliable measurements.
