Description

The RP-C10-ST Force Sensitive Resistor operates on the principle of piezoresistivity, where applied force reduces the internal resistance of a conductive polymer film. This change in resistance is inversely proportional to the force, allowing it to function as both an analog force sensor and a programmable threshold switch. The sensor’s signal can be conditioned via a simple voltage divider to provide a readable analog voltage for microcontrollers.

Designed with a minimal 0.4mm thickness and a protective, waterproof layer, this FSR is suited for integration into tight spaces and environments requiring some moisture resistance. Its quick response time makes it applicable for capturing rapid pressure changes, while its durable build ensures reliability across repeated force cycles in prototyping and end-use applications.

Key Features

  • Thin-Film FSR Technology: Provides analog resistance output directly proportional to applied force for precise measurement.
  • Rapid Dynamic Response: Sub-10ms response time enables accurate capture of quick pressure changes and taps.
  • Optimized Form Factor: Ultra-slim 0.4mm thickness with integrated adhesive backing for seamless mounting.
  • Robust Sensing Element: Durable conductive polymer Matrix ensures consistent performance and long-term stability.
  • Simple Two-Terminal Interface: Functions as a variable resistor, requiring only a basic pull-up/pull-down resistor for microcontroller interfacing.
  • Broad Force Range: Effectively measures forces from light touch (20g) up to substantial pressure (2kg).

Applications

  • Interactive prototype touch and pressure sensing for Arduino/Raspberry Pi projects
  • Robotic gripper and end-effector tactile feedback systems
  • Wearable electronics for gait analysis and foot pressure distribution mapping
  • Musical instrument interfaces and expressive MIDI controllers
  • Industrial equipment for presence detection and lightweight force monitoring

Frequently Asked Questions

How do I connect this FSR to an Arduino or Raspberry Pi?

Connect one FSR terminal to your board's analog input pin and the other to ground. Place a fixed-value resistor (typically 10kΩ) between the analog pin and your logic voltage (3.3V or 5V) to create a voltage divider. The analog reading will decrease as applied force increases. Ensure your code accounts for the inverse relationship between resistance and the measured voltage.

What is the difference between using this as an analog sensor versus a switch?

As an analog sensor, the continuous resistance change provides a proportional force measurement. As a switch, you set a threshold in your microcontroller's code; when the analog reading passes this threshold (indicating sufficient force), it triggers a digital ON/OFF event. The switching point is fully software-configurable based on your voltage divider readings.

Can this sensor measure dynamic or impact forces?

Yes, its sub-10ms response time allows it to capture dynamic pressure changes effectively. However, for quantifying high-speed impacts, the sensor's inherent damping and the system's signal conditioning bandwidth must be considered. It is best suited for measuring applied pressure, touch events, and slower dynamic loads rather than precise impact force profiling.

Is the adhesive backing strong enough for permanent mounting?

The integrated adhesive is suitable for secure mounting in most prototyping and light-duty applications. For permanent installation in high-vibration environments or on uneven surfaces, supplementing with mechanical fasteners or a stronger industrial adhesive is recommended to ensure long-term sensor placement and consistent contact.
