The RP-C18.3-LT is a circular flexible thin-film pressure sensor, 18.3mm in diameter, designed for highly sensitive detection of both static and dynamic force. When pressure is applied to the active area, resistance decreases proportionally — making it straightforward to interface with a microcontroller's ADC for pressure or force measurement.

Ultra-thin at 0.4mm, it's flexible enough for embedding in wearables, medical devices, footwear, and bed monitoring systems, while remaining durable for over one million actuation cycles.
