Question: I have an application which as an air gap between Capsense button and Overlay Material. Are there any good solution to increase the sensitivity?
Answer:
Firstly, our capsense is not recommended to have any air gap between the capsense button PCB and an Overlay material.
If your application demands an air gap, We suggest you to connect a spring between the capsense button and the overlay, this should enable to detect it as a button with better sensitivity.
For more information you may have a look at an application note "Using Springs as CapSense Sensors AN44999"
This application note considers the possibility of using springs as sensors. A comparison with solid conductive sensors and recommendations for the practical usage of springs are also discussed.
