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.

Jargon buster
Plain-language definitions for the technical terms used above.
- ADC
- An analogue-to-digital converter reads a changing voltage and turns it into a number the microcontroller can use. It matters when connecting analogue sensors such as light, sound, or variable-resistor sensors.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
