Force Sensitive Resistors (FSRs) have carved out a niche in a variety of industries, from consumer electronics to healthcare, thanks to their unique ability to detect varying levels of pressure. In recent years, the FSR market has seen an impressive growth trajectory, driven by advancements in sensor technologies, increasing demand for smart products, and the growing need for more sophisticated user interfaces. In this comprehensive article, we will explore the current market landscape for Force Sensitive Resistors, including key growth drivers, challenges, applications, and future projections.
What Are Force Sensitive Resistors (FSRs)?
Force Sensitive Resistors (FSRs) are a type of sensor that change their electrical resistance when subjected to force or pressure. These sensors are typically made from a polymer-based material that exhibits conductive properties. As pressure is applied, the resistance decreases, allowing for accurate pressure measurement. FSRs are widely used due to their flexibility, affordability, and ease of integration into various applications.
How FSRs Work
The fundamental working principle behind an FSR is based on the relationship between the applied force and the change in resistance. In most cases, FSRs have a thin, flexible substrate with a conductive layer. When force is applied, the physical deformation of the sensor changes the contact resistance between the layers, thus altering the electrical current passing through the device. This change can be easily measured and converted into a usable output for a wide range of applications.
