FORCE SENSITIVE RESISTOR – SQUARE

Description:

A force-sensitive resistor (FSR) is a type of sensor that can detect and measure the force or pressure applied to its surface. The "square" FSR refers to a specific shape or form factor of the sensor, which is typically square in shape. The square FSR consists of a conductive polymer material sandwiched between two layers of conductive electrodes. When pressure or force is applied to the surface of the FSR, the conductive polymer material changes its resistance. This change in resistance can be measured and used to determine the magnitude of the applied force. The square FSR is designed to provide a relatively even distribution of force sensitivity across its surface. This means that regardless of where the force is applied within the sensor's square area, it will provide a consistent and reliable response. These sensors are commonly used in various applications, such as touch-sensitive input devices, robotic grippers, and medical devices. They can be interfaced with microcontrollers or other electronic circuits to convert the change in resistance into a measurable electrical signal. Overall, the square force-sensitive resistor offers a simple and versatile solution for detecting and quantifying applied forces or pressures in a wide range of applications.

Specification:

• Sensing Area: The square FSR has a sensing area on its surface where the force or pressure is applied. The size of the sensing area may vary depending on the specific model and manufacturer.
• Force Range: FSRs are available in different force ranges, which determine the minimum and maximum forces that can be detected. The force range should be suitable for the intended application.
• Resistance Range: FSRs exhibit a change in resistance proportional to the applied force. The resistance can vary from a high value (in the megaohms range) when no force is applied, to a low value (in the tens or hundreds of ohms range) when maximum force is applied. The exact resistance range depends on the specific FSR model.
• Sensitivity: FSRs have a sensitivity value that describes how much the resistance changes per unit of force applied. This sensitivity is typically specified in units like kilohms/Newton or ohms/pound. Higher sensitivity means the FSR can detect smaller force variations.
