Flexible Pressure Sensor Walfront Thin Film Design

Description

Product Overview

The RP‑C type pressure sensor from Walfront is a flexible thin‑film device that converts applied pressure into a measurable change in resistance. Constructed from high‑quality polymer film, the sensor measures just 0.39 × 0.98 × 0.04 in and weighs only 0.4 oz, making it ideal for space‑constrained applications. It operates at 1 V without the need for batteries, delivering a quick response to both static and dynamic pressure changes. Key specifications include a spout height of 1 cm, single‑sensitive‑area design, and a pressure‑dependent variable resistance that can act as a switch at a predefined threshold.

Usage

The sensor excels in environments where precise force detection is critical. Common use cases include bedside patient monitoring, sleep‑tracking mattresses, smart footwear that measures gait pressure, industrial counters, and medical equipment that requires reliable pressure feedback. Its flexible nature allows it to conform to curved surfaces, making installation on wearable fabrics or irregular machine parts straightforward.

FAQ

What is the pressure range of the RP‑C sensor?

The sensor is designed for low to moderate pressures typically encountered in wearable and medical applications, roughly up to 1 MPa. Exact limits are provided in the technical datasheet.

Can the sensor be used in humid environments?

Yes. The polymer film is sealed with a moisture‑resistant coating, allowing reliable operation in high‑humidity settings such as hospitals or outdoor wearables.

How is the sensor calibrated?

Calibration is performed by applying known pressures and recording the corresponding resistance values. Walfront supplies a calibration curve for each batch to ensure consistency.

Is a special installation method required?

No special tools are needed. The sensor can be adhered with standard conductive adhesive or mounted using a simple clip, depending on the application.

What is the expected lifespan of the sensor?

Under normal operating conditions, the sensor maintains its performance for over 10,000 pressure cycles, making it suitable for long‑term deployments.
