What Is a Force Sensitive Resistor?
A Force Sensitive Resistor (FSR) is a polymer-thick-film device that changes its electrical resistance when pressure is applied. The harder the pressure, the lower the resistance — allowing the sensor to accurately measure applied force or touch.
Unlike traditional mechanical switches, FSRs are:
- Thin and flexible — ideal for integration into compact devices.
- Durable and cost-effective — suitable for high-volume applications.
- Responsive and reliable — offering analog feedback instead of binary signals.

Custom Design Options for Force Sensitive Resistors
Every application has its own performance requirements. That’s why SOUSHINE provides full customization across mechanical, electrical, and aesthetic parameters.
🔹 Shape and Dimensions
Choose from round, square, strip, ring, or irregular geometries to match your product’s interface.
🔹 Force Range
Adjustable from 0.2N to over 100N, covering light touch detection to high-force measurement.
🔹 Output Type
Analog or digital signal output, compatible with Arduino, Raspberry Pi, or dedicated microcontroller circuits.
🔹 Connector Type
FPC, solder pads, or plug-in terminal options for seamless assembly integration.
🔹 Mounting Options
Adhesive backing, embedded structures, or laminated modules to simplify installation.
Whether you’re creating a wearable device, industrial control panel, or robotic gripper, we can engineer your FSR to meet specific design targets in sensitivity, response time, and environmental resistance.
Material Selection and Layer Structure
The core performance of a force sensor depends on material choice and layer design.
SOUSHINE utilizes high-precision conductive inks, PET film, and carbon-based polymer composites to ensure both sensitivity and durability.
A standard FSR typically includes:
- Top conductive layer (silver/carbon ink)
- Spacer adhesive layer
- Active sensing layer (semi-conductive polymer)
- Bottom substrate film
We also support custom laminations, such as:
- Waterproof coatings
- High-temperature resistance
- UV-stable encapsulation
- Anti-corrosion plating
By controlling each layer’s material and thickness, we optimize your sensor’s response curve, repeatability, and longevity under repeated use.

FAQs
What is a Force Sensitive Resistor?
A Force Sensitive Resistor, or FSR, is a special kind of sensor that measures pressure or touch. When you press on it, the sensor changes its electrical resistance. This means it can tell how hard something is being pressed. Unlike regular buttons that just say ‘on’ or ‘off’, FSRs can give different levels of response depending on how much pressure is applied. This makes them useful in many devices, from toys to medical equipment!
What are the different shapes and sizes of FSRs?
Force Sensitive Resistors come in various shapes and sizes to fit different products. You can find them in round, square, strip, or even irregular shapes! This customization helps engineers choose the best fit for their designs, whether it’s a round button on a game controller or a long strip for a medical device.
How do I know what force range I need for my FSR?
The force range of an FSR tells you how light or heavy of a touch it can detect. For example, you might choose a sensor that can detect very light touches (around 0.2N) if it’s for something like a wearable device. On the other hand, if you need to measure heavy weight, you would choose one that can handle more than 100N. It all depends on how you plan to use it!
What types of connections do FSRs use?
FSRs can connect to devices in several ways. Common options include using FPC (Flexible Printed Circuit), solder pads that you can attach wires to, or plug-in terminals that allow for easy connections. This variety makes it simple to integrate FSRs into many different kinds of projects!
How are FSRs made and what materials are used?
Making a Force Sensitive Resistor involves using various materials. Usually, they have a top conductive layer made from special inks, a spacer layer, an active sensing layer made from semi-conductive materials, and a bottom substrate film. SOUSHINE can even customize materials to make them waterproof or resistant to heat and other tough conditions!
What are OEM and ODM services for force sensors?
OEM stands for Original Equipment Manufacturer, and ODM stands for Original Design Manufacturer. These services mean that SOUSHINE can help other companies design and make their force sensors. They provide full support, from creating custom designs to large-scale production while ensuring quality and confidentiality!
Why should I choose SOUSHINE for my FSR needs?
SOUSHINE has over 15 years of experience making force sensors and offers many benefits. They use advanced materials for better durability and performance, carefully control the manufacturing process for consistent quality, and can handle large orders for different industries.
