FAQs

What is Swept Frequency Capacitive Sensing (SFCS) and how does it work?

Swept Frequency Capacitive Sensing is an advanced form of capacitive sensing that operates by sweeping a range of frequencies across a sensor electrode. Instead of using a single frequency, it measures the capacitive response at multiple frequencies. This method allows the system to distinguish between the actual capacitance change caused by a target object and parasitic capacitances or environmental noise, which appear differently across the frequency spectrum. Sophisticated algorithms then process this multi-frequency data to extract a highly accurate and stable measurement of capacitance, enabling reliable detection of touch, proximity, or material properties even in challenging conditions.
