a capacitor to power the microcontroller for a few milliseconds? actually, if the goal is to detect a reset operation by unscrewing: while unscrewing and shortly after the circuit is open, the previously contacting electrodes are still close by, such that it can be powered capacitively while it realizes it is being reset... this is probably noticable by measuring the change in complex impedance
