What Is an Integrated Sensor?

Integrated sensors are sensors made using silicon semiconductor integration processes, so they are also called silicon sensors or monolithic integrated sensors. The analog integrated sensor was introduced in the 1980s. It is a special IC that integrates the sensor on a chip and can complete the measurement and analog signal output functions. The main characteristics of analog integrated sensors are single function (only measuring a certain physical quantity), small measurement error, low price, fast response speed, long transmission distance, small size, micro power consumption, etc., suitable for long-distance measurement and control, no need to perform Non-linear calibration and simple peripheral circuits.

Advances in technology in the field of sensing. Today's sensor elements used to monitor or control systems require accuracy, reliability, and support for practical application inputs. This is one of the most challenging tasks in the product development cycle. Therefore, many designers do not hesitate to choose to buy off-the-shelf products or customize pre-integrated sensor modules, which shows that integrated sensors will be an inevitable trend in the future.

Many sensor suppliers entrust most of the tasks of designing, testing, and manufacturing sensor components to third-party suppliers, which can maximize the limited resources of the engineering design team and shorten the time to market. Nevertheless, there are still many key decisions that need to be made by the designer, and these key decisions will have a significant impact on product performance, reliability, and cost. To help design the best system for a specific application, let's first analyze the pre-integrated sensing elements, especially the advantages that different sensing elements can provide, and then familiarize yourself with some of the main issues that must be considered. Even experienced sensor engineers have to admit that designing sensing elements that provide accurate and reliable data for the actual application conditions of medical equipment, process control, or other factory automation equipment is the most time-consuming and time-consuming part of the product development cycle. Expensive work one. In large part, this is because sensor design is a process of interdisciplinary collaboration that requires design teams to consider many electrical, mechanical, and manufacturing process issues.

Once you determine which sensing element is best for your application, you must decide how to integrate it with the rest of the system. This process involves pairing the sensor with a suitable combination of signal conditioning circuits, terminals, and interface connectors. Next, you need to decide whether there is an off-the-shelf package that can accommodate your assembly, or a custom package based on application space and environmental requirements. Custom packages may integrate one or more sensors and other components to create higher-level assemblies, such as pressure sensors with integrated tubing for use in blood analyzers and ventilators. Of course, with the advancement of sensor design, its test plan must also keep pace with the times. Your design must ensure that after the final assembly is inherited into the main system, the product will operate accurately and reliably. The trend of integrated sensors can be seen, and sensor technology will continue to improve. ^[1]
