Description

The SOUSHINE FSR408 is a single-zone Force Sensing Resistor (FSR) based on polymer thick film (PTF) technology. When force is applied to its 15mm x 100mm active area, the sensor exhibits a predictable decrease in electrical resistance, providing an analog signal proportional to the applied pressure. This robust construction ensures reliable performance across millions of cycles.

Designed for durability and precision, the FSR408 operates effectively in applications requiring detection of presence, grip, or pressure. Its ultra-thin form factor and customizable nature make it ideal for embedding into panels, grips, and interfaces where space is constrained and reliable tactile feedback is essential for system control and safety interlocks.

Key Features

  • Polymer Thick Film (PTF) Sensing Element: Provides a robust, flexible interface with a predictable force-resistance relationship.
  • Wide Dynamic Range: Covers forces from light touch (0.1N) up to 10N, enabling both binary detection and analog force measurement.
  • High Repeatability & Long Life: Delivers consistent readings with less than 2% variance and is rated for up to 10 million actuations.
  • Minimal Profile: At only 0.40 mm thick, it integrates invisibly into products without adding bulk.
  • Simple Two-Wire Interface: Functions as a variable resistor, easily interfaced with microcontrollers (Arduino, Raspberry Pi, ESP32) via a basic voltage divider circuit.
  • Durable & Flexible Substrate: Withstands bending and mechanical stress, suitable for dynamic applications.
  • High-Value Build: Optimized performance-to-cost ratio for volume integration in consumer electronics, medical devices, and industrial controls.

Applications

  • Tactile User Interface (UI) Panels: Implementing pressure-sensitive buttons and sliders in automotive dashboards, appliance controls, and musical instruments.
  • Medical Device Safety & Monitoring: Detecting patient presence in beds/chairs, monitoring grip force on handheld tools, or sensing occlusions in infusion pumps.
  • Robotics & Industrial Grippers: Providing grip force feedback and slip detection for robotic end-effectors and collaborative robots (cobots).
  • Ergonomic & Biomechanical Analysis: Measuring pressure distribution in footwear, seating, or handheld equipment for product design and therapy.
  • Tool & Equipment Safety Interlocks: Differentiating between a firm grip and an accidental touch to enable or disable machine operation.

Frequently Asked Questions

How do I interface the FSR408 with an Arduino or microcontroller?

The FSR408 is a two-wire variable resistor. Connect one pin to your microcontroller's analog input pin (e.g., A0) via a voltage divider circuit (typically a 10kΩ pull-down resistor). The other pin connects to your logic voltage (3.3V or 5V). The analog reading will vary inversely with the applied force. Calibration is required to map the ADC reading to a specific force value.

What is the difference between sensitivity range (0.1N-10N) and maximum force (10kg)?

The sensitivity range (0.1N to 10N) indicates the forces over which the sensor provides a useful, measurable change in resistance, ideal for precise detection. The maximum force (10kg, ~98N) is the mechanical limit the sensor can withstand without permanent damage. Operating consistently above the 10N sensitivity range may reduce accuracy and longevity.

Can the FSR408 be cut or trimmed to a custom size or shape?

No, the active sensing area of the FSR408 is defined by the 15mm x 100mm printed pattern. Cutting or trimming the sensor will destroy its functionality. For custom sizes, you must select a different FSR model or consult the manufacturer for a tailored solution. The sensor is flexible but not user-customizable post-manufacture.

What is the expected lifespan and how does actuation force affect it?

The sensor is rated for up to 10 million actuations when used within its specified force range. Exceeding the 10N sensitivity range or applying Sharp Microelectronics, point-load impacts can significantly reduce this lifespan. For maximum durability, ensure force is applied evenly across the active area and within the recommended operational limits.
