13cm Force Sensitive Resistor (FSR) Strip Sensor

What is it?

Pressure isn't always applied to a single point. Sometimes you need to know where someone is pressing, gripping, leaning, or stepping. This extra-long 13cm Force Sensitive Resistor (FSR) Strip Sensor makes it easy to add touch and force sensing to projects where a standard round FSR simply isn't enough.

The sensor changes its resistance as pressure is applied anywhere along its active sensing strip. Its long, narrow profile makes it perfect for detecting squeezes, presses, grips, and distributed force across elongated surfaces. Because it's thin and flexible, it can be tucked underneath panels, fabrics, foam, silicone, or other soft materials without adding significant thickness.

Whether you're building interactive art, wearable devices, robotics, musical instruments, assistive technology, or experimental user interfaces, this sensor provides an easy way to make your project respond naturally to touch and pressure.

Features:

• 13cm active sensing length
• Thin, lightweight, and flexible construction
• Analog force-sensitive output
• Easy interface with Arduino, ESP32, Raspberry Pi, and other microcontrollers
• Ideal for custom pressure-sensitive interfaces

Unique Project Ideas:

Smart Handle Grip – Detect how firmly a user grips a joystick, bicycle handle, exercise equipment, or power tool.

Pressure-Sensitive Slider – Place beneath a flexible overlay to create a soft linear control for volume, brightness, or scrolling.

Electronic Musical Instrument – Sense finger pressure on custom keyboards, MIDI controllers, or expressive instruments.

Sword or Lightsaber Grip Sensor – Detect how tightly the handle is held for immersive gaming props or cosplay electronics.

Robotic Gripper Feedback – Measure gripping force to prevent crushing delicate objects.

Interactive Furniture – Hide beneath armrests or cushions to detect when someone leans or rests their arm.

Smart Shelf Sensor – Detect when an object has been placed on a narrow shelf or display stand.

Foot Pressure Strip – Integrate into a narrow foot pad for balance experiments or interactive installations.

Wearable Compression Sensor – Sew into straps, belts, gloves, or braces to monitor applied pressure.

Drawer or Door Detection – Mount behind a gasket to detect when a compartment is fully closed with adjustable pressure sensitivity.

Gesture-Based Interface – Detect squeezes or presses along a soft control strip without mechanical switches.

Interactive Toys & Escape Rooms – Hide under props to create pressure-triggered puzzles and secret mechanisms.

Great For:

• Arduino projects
• ESP32 IoT devices
• Robotics
• Interactive installations
• Human-computer interfaces
• Musical controllers
• Smart furniture
• Wearables
• Research and prototyping
• Educational STEM projects

Unlike traditional pushbuttons that simply detect ON or OFF, this FSR provides proportional force measurements, allowing your projects to react differently depending on how gently or firmly pressure is applied. The long sensing area opens up countless creative possibilities for building intuitive, touch-responsive electronics.
