Circular Force Sensor with Extended Leads (Diameter: 7.6mm, 30g-1.5kg, Thickness: 0.3mm)

RP-C7.6-LT Thin Film Pressure Sensor is a circular flexible pressure sensing element with a 7.6mm active area designed for highly sensitive force detection in compact systems. Built using ultra‑thin films and nanometer-scale pressure‑sensitive materials, this tactile sensing component converts applied force directly into resistance changes. A lightweight structure and flexible construction allow seamless integration into wearable products, robotics interfaces, and embedded electronics. Fast electrical response and long mechanical lifespan enable reliable monitoring of both static and dynamic pressure events, supporting applications such as smart footwear, bed occupancy monitoring, medical equipment interfaces, and intelligent pressure switches.

Ultra-Thin Flexible Sensing Structure

This flexible force sensing component uses layered thin-film construction with a conductive circuit layer and a nanometer pressure-sensitive layer bonded together through double-sided adhesive. When external force presses the active region, conductive paths form between layers, producing measurable resistance variation. The extremely thin 0.3mm structure allows installation beneath surfaces or inside compact mechanical assemblies where conventional load sensors cannot fit, making the sensing film suitable for embedded electronics, wearable technology, and space‑constrained smart products.

Fast Response for Dynamic Force Detection

High sensitivity combined with rapid electrical response enables accurate detection of both static loads and dynamic pressure signals. Activation time below 0.01 seconds and response time under 10ms support real‑time monitoring of rapid force changes. Stable performance within frequencies up to 10Hz enables reliable signal acquisition in motion sensing systems, touch detection interfaces, and pressure-triggered control mechanisms where quick reaction and consistent electrical behavior are required.

Durable Design for Long-Term Monitoring

Advanced conductive materials and mechanically resilient thin films provide long operational lifespan exceeding one million actuations. Low drift under sustained load and minimal hysteresis ensure repeatable readings during continuous pressure monitoring tasks. Resistance output decreases proportionally with applied force, allowing simple integration with analog measurement circuits or microcontroller-based data acquisition systems used in smart healthcare devices, intelligent footwear systems, and industrial force detection tools.

Compact geometry, fast response characteristics, and flexible construction make this pressure sensing film suitable for pressure-trigger switches, wearable force monitoring, medical detection equipment, smart mattress systems, and embedded tactile sensing modules used in robotics or interactive electronics.
