Description

The FlexiForce A201-100 operates on the piezoresistive principle, where an applied force to its 9.53 mm diameter active area causes a predictable decrease in the sensor’s internal resistance. This analog resistance change can be conditioned via a simple voltage divider or operational amplifier circuit to produce a voltage signal proportional to the applied load, compatible with microcontroller ADCs on platforms like Arduino, Raspberry Pi, or industrial PLCs.

Constructed on a durable polyester substrate, the sensor maintains its electrical characteristics when flexed, only responding to direct pressure on the sensing zone. Its thin profile and flexibility allow it to be mounted on curved surfaces or within tight spaces for applications from product testing to embedded force feedback systems.

Key Features

  • Piezoresistive Thin-Film Technology: Delivers a highly linear resistance response to applied force for accurate measurement.
  • Ultra-Thin & Flexible Form Factor: 0.203 mm thickness and flexible polyester construction enable installation in confined or curved spaces.
  • Wide Force Range Capability: Nominally rated for 0-100 lbs (445 N), with circuit adjustments possible to measure forces up to 1000 lbs.
  • Stable Performance: Engineered for low hysteresis and minimal drift over time and temperature.
  • Standardized Connector: Features a 3-pin male square pin connector (2.54 mm pitch) for reliable electrical connection.
  • Broad Environmental Tolerance: Operates reliably across an extended temperature range from -40°C to +60°C.

Applications

  • Embedded Force Feedback: Integration into robotics grippers, prosthetic devices, or human-machine interfaces for precise force control.
  • Test & Measurement Equipment: Calibration and verification of applied forces in manufacturing QA, material testing, and product validation jigs.
  • Consumer Electronics Development: Prototyping force-sensitive controls, buttons, or input devices for OEM products.
  • Biomechanical & Medical Research: Measuring contact pressures in gait analysis, rehabilitation devices, or ergonomic studies.
  • Industrial Process Monitoring: Monitoring clamping forces, assembly press fits, or material handling loads.

Frequently Asked Questions

How do I interface the FlexiForce A201-100 sensor with a microcontroller like Arduino?

The sensor acts as a variable resistor. Create a simple voltage divider circuit by connecting one sensor lead to your microcontroller's analog input pin (via a pull-up resistor to Vcc, typically 10kΩ to 1MΩ) and the other lead to ground. The analog voltage read will decrease as force increases. For optimal linearity and range adjustment, consider using an operational amplifier in a non-inverting configuration.

What is the function of the three pins on the connector?

The 3-pin male square pin connector has only two active pins; the center pin is inactive and not connected internally. The two outer pins are the electrical leads of the piezoresistive element. You only need to connect to these two active pins to complete the sensing circuit.

Can this sensor measure forces above its rated 100 lb range?

Yes, the sensor can measure forces up to approximately 1000 lbs by modifying the conditioning circuit. To extend the range, reduce the drive voltage applied across the sensor and use a smaller feedback resistor in your amplifier circuit. This shifts the sensor's operating point on its resistance curve to accommodate higher forces while maintaining output signal resolution.

Is the sensor's output affected by bending or flexing without direct pressure?

No, the FlexiForce sensor's resistance change is specifically triggered by pressure applied directly to its circular sensing area. Bending or flexing the polyester substrate without applying force to the active area will not produce a significant change in resistance, making it suitable for applications on moving or curved surfaces.
