Force Sensitive Resistor Basics

How FSRs Work

Resistance Change Principle

When you press a force sensitive resistor, its resistance goes down. If you press harder, the resistance gets even lower. This change helps you know how much force you use. You can use this for many ways to measure force. SOUSHINE’s technology is special because it is very accurate and uses little power. The sensor reacts fast and works well in lots of places.

Construction and Materials

A force sensitive resistor has a bendable base. On top, there is a spacer and a special layer that carries electricity. When you press, these layers touch and let electricity flow. The path changes if you press harder or softer. SOUSHINE uses tough materials, so their sensors last longer and can handle more use. You can choose from many shapes and sizes for your project.

Tip: If you want a sensor that is easy to add, SOUSHINE’s FSRs make it simple.

Here is a quick chart showing how SOUSHINE’s technology compares:

Common Applications

Automotive

You find force sensitive resistors in car seats. They help tell if someone is sitting down. This helps with airbags and seatbelt reminders. FSRs also help with touch controls on dashboards.

Healthcare

In hospitals, force sensitive resistors help watch patients. They sense if a patient moves or leaves the bed. You also see them in pumps to check for blockages.

Robotics

Robots use force sensitive resistors to feel how hard they grip things. This helps robots pick up items without breaking them. FSRs also help robots know when they touch something.

Consumer Electronics

You use force sensitive resistors in game controllers, touchpads, and musical instruments. They let you control things by pressing harder or softer. This makes using devices more fun.

Here are other ways to use a force sensitive resistor:

• Telling if a touch is on purpose or by accident.
• Giving feedback based on how hard you press.
• Making tools safer by knowing a grip from a touch.
• Finding the center of force with many sensors.
• Sensing if someone is in a bed, chair, or medical device.
• Checking for liquid blockages in tubes or pumps.

Many industries use FSRs because they are small, simple, and work in lots of places where you need to measure force.

Choosing the Right FSR

Application Needs

You should pick a sensor that fits your project. First, think about what you want the sensor to do. Do you need it to feel a soft touch or a hard press? Will it go in a small spot or a big one? Every project is different and needs its own sensor. Here is a table to help you see what matters:

If you want a sensor for a robot hand, you might need a small and sensitive one. If you need one for a hospital bed, you may want a bigger sensor that can feel a person’s weight. SOUSHINE has many shapes and sizes, so you can find one that works for your idea.

Budget Considerations

How much money you have is important when picking a sensor. Some sensors cost more because they are more accurate or have special features. If you only need simple force sensing, you can choose a cheaper sensor. Buying a lot at once can make each sensor cost less. SOUSHINE gives lower prices if you buy many at the same time.

Think about which features you really need. It is smart to pay more if your project needs extra features. If not, a basic sensor can help you save money.

💡 Tip: Write down the features you must have before shopping. This way, you will not pay for things you do not need.

First-Time Buyer Tips

If you have never bought a sensor before, try a sample or a small pack first. This helps you test the sensor in your project before buying more. Look at the datasheet for size, force range, and wiring info. Ask the seller if you are not sure how to use the sensor.

Try to match the sensor’s force range to your project. If the range is too small, it might not work well. If the range is too big, it might not feel soft touches.

You can read reviews or ask other people what they think. Many sellers, like SOUSHINE, can help you pick the right fsr for your project.

🛠️ Note: Testing the sensor in your real project helps you avoid problems later.
