Operating sensor with a DC offset.

The next requirement for my application is that the sensor to be operated with a DC offset to attract charged particles. Just being being lazy and hoping someone can suggest the easiest route for doing this so I don't have to think too hard.

Thanks

    openQCM quartz is not grounded. Honestly I do know if it is possible to apply a DC offset.... let me to try before better answer to your question.

    Thank you for trying. It looks like floating the shield with external power supplies and using opto-isolators to couple the signal to the Arduino wouldn't be all to painful.
