Touch under high electrostatic noise

We have an application where the user pressing buttons is under high electrostatic noise from known sin wave frequencies in the range of 50-74 kHz. Competing touch technologies have failed to operate reliable so far. Could ti touch technology perform better under these specific conditions ?

  • Hello Hans,

    The Application Report sbaa155a located at:

    has good information on using a touch screen in a noisy environment.

  • The report mentioned is about resistive touch screen technology. That's not at all what I'm dealing with. I have buttons where ti captivate technology could be applicable ...., in an environment where there's high voltage electroSTATIC noise. The application is a sunbed where the user is on an isolated glass plate and sandwiched between uv lamps which are now driven by an electronic ballast at relative high frequency of 50-75 kHz, making the user a capacitor plate. So there's a high capacitive coupling from lamps to user. This user has now difficulties pressing the touch buttons, at least in the case of some competing technologies.

    So, thats the case. Is there any reason why captivate technology could perform better ?
