The following design modifications were applied (see Figure 6):

●

A good voltage dimensioned serial resistor was used.

●

Sufficient isolation distances between the electrode and neighboring PCB tracks was

implemented.

●

A spark gap was built to route part of the ESD energy away from the electrode to the

application GND.
