Force Sensor Circle Shape

Force Sensor (Circular FSR)

The circular Force Sensitive Resistor (FSR) is a pressure sensor that changes its resistance based on the applied force. It is widely used for detecting touch, pressure, and weight in interactive electronics and embedded systems.

Key Features

• Force Detection: Resistance decreases as pressure increases
• Circular Sensing Area: Uniform detection across the surface
• Analog Output: Provides continuous force-based readings
• Thin & Flexible: Easy to integrate into compact designs
• Fast Response Time: Real-time pressure detection
• Low Power Consumption: Suitable for portable applications

Applications

• Touch & Pressure Sensing: Interactive input systems
• Weight Detection: Basic force measurement applications
• Robotics: Grip force sensing
• Wearable Devices: Pressure monitoring
• DIY Electronics: User input and feedback systems

Technical Specifications
