Hi,
I came across the method to implement the capacitive touch using spring as a capsense sensor.
Can I get the any reference document to select the spring specification such as spring dimeter, spring height, thickness of metal spring, turns in spring.... and how it basically affect sensitivity.
I want to achieve sensitivity over 7mm thickness(4mm overlay + 3mm spacer) with around 12mm sensor area & 5mm distance between two sensors. There are multiple sensors on same board.
recommendation for selection criteria of spring would be highly appreciated.
Thanks in advance.
Solved! Go to Solution.
