1. An electronic system ( 500 ) for a system for neural applications ( 100 ) comprising at least one first connector element ( 510 ) and at least one second connector element ( 520 ), the first connector element ( 510 ) being configured such that the electronic system ( 500 ) is connectable or connected to a controller ( 110 ) which is at least configured to provide at least one electrical signal via one or more stimulation outputs, the second connector element ( 520 ) being configured such that the electronic system ( 500 ) is connectable or connected to a lead ( 300 ) for neural stimulation, wherein the electronic system comprises at least one leakage current detection means ( 550 ), wherein the at least one leakage current detection means ( 550 ) is configured such that a leakage current is detectable and/or preventable, and wherein the electronic system ( 500 ) is configured such that by design the at least one electrical signal provided via the one or more stimulation outputs has a substantially zero DC content or by design has a DC current that is inherently limited to substantially zero.
