Introduction

Flexiforce Pressure Sensor - 100lbs is a thin piezoresistive force‑sensing strip designed to convert applied pressure into measurable resistance changes. Based on piezoresistive technology, this flexible force sensing element exhibits extremely high resistance with no load and decreases toward ~300kΩ as pressure increases. The sensing structure remains mechanically flexible while maintaining stable electrical behavior during bending, with measurement triggered only when force is applied to the circular sensing area. Breadboard‑friendly 0.1" pin spacing simplifies integration with prototyping platforms such as Arduino or other embedded controllers for interactive pressure‑aware projects.


Wide Dynamic Force Detection

This flexible pressure detection module supports a measurement range from 0 to 100lbs (approximately 440N), covering light touch interactions through moderate load sensing. Resistance changes proportionally with applied force, enabling reliable detection of presence, weight distribution, and impact intensity. Such characteristics make the sensing strip useful for robotics contact detection, smart surface monitoring, and experimental load measurement systems where relative force variation provides actionable input signals.


Ultra‑Thin Flexible Construction

The sensing strip measures approximately 216 × 14mm with a narrow profile that allows installation beneath surfaces or inside compact mechanical assemblies. Mechanical flexibility allows bending without altering electrical resistance characteristics, ensuring consistent readings while embedded within wearable devices, robotic grippers, pressure‑sensitive floors, or interactive installations. Pressure measurement occurs exclusively on the 9.53mm circular sensing area, ensuring predictable force localization during operation.


Fast Response for Real‑Time Interaction

A response time below 5 ms enables rapid detection of changing loads or touch events. This quick electrical response allows the force sensing strip to capture dynamic pressure changes such as impacts, footsteps, or robotic contact events. Combined with the low operating current requirement of 2.5mA, the sensing component integrates well into low‑power embedded systems, portable data loggers, and responsive human‑machine interfaces.


This flexible force measurement sensor supports a variety of embedded sensing tasks including presence detection, weight estimation, contact sensing, and impact monitoring. Integration into interactive prototypes, robotics experiments, and STEM Education projects enables real‑time force feedback for smart environments, pressure‑aware controllers, and experimental measurement platforms.
