Force sensing resistors: These are special sensors that can tell how much pressure, or force, is being pressed on them. They are employed in a wide range of tools and technology to make them work better.
Understanding the Basics
In order to appreciate how a force sensing resistor works, we must first learn about resistors. Resistors are components in electronics that cut off the flow of electricity. This makes it difficult for electricity to pass through them. The reason why force-sensitive resistors are special is they vary how much they resist electricity in correlation to the amount of force you apply to them.
Exploring the Technology
Force sensing resistors are constructed of a material that alters in the midst of the application of force. The substance is typically sandwiched between two materials that are capable of conducting electricity. If you press against the resistor, its material is squeezed and that changes how much it resists electricity. The shift is measured to determine the magnitude of the force that is applied.
A Step-by-Step Explanation
The material inside a force sensing resistor gets squooshed when you push on it.
This squeezing alters the degree to which the material resists electricity.
The change is measured by the piece of equipment attached to the resistor.
The device leverages that data to determine how much force is being exerted.
This information can govern different aspects of the device, such as the speed at which it operates, or the amount of power it consumes.
Real-World Examples
FSR strips are included in various devices. That is, in touch screens, it can tell how hard you are pushing when you touch the screen using force sensing resistors. This helps the device understand where on the screen you are touching and what to do based on your touch.
A second example is that of medical devices. Prosthetic limbs may be improved by including force sensing resistors that can be used in controlling the limb. By sensing the force of the push, the prosthetic limb can move more accurately and naturally.
Performance and accuracy improvement
Force sensitive resistors improve worth of devices and are more accurate. For example, video game controllers can read how hard a player presses a button. This will make the game play more accurate and provide a better gaming experience.
Force sensing resistors allow robots to play with their world. By feeling how much force it is applying, a robot can tell when it has grabbed something or how hard to press when doing a task.
So, keypad matrix force sensing resistors are significant, as they make devices sense and react to pressure or force. By learning how they work and where they are used, we can understand how these magnetic vortices lead to increased performance and accuracy in a wide variety of devices and systems.
