Multi-part sensing electrode connector

A multi-part sensor interconnect portion, comprising:

• a flexible substrate;
• one or more connectors positioned on a side of the further flexible substrate;
• one or more electrically conductive contact structures positioned on the same side of the flexible substrate as the one or more connectors are positioned, wherein the contact structures electrically interface with portions of one or more electrode traces on an electrode portion when the connectors mate the further connectors, the electrode portion further comprising an enclosure of further portions of the electrode traces, one or more electrodes each connected to one of the electrode traces, and one or more further connectors each configured to detachably mate to one of the connectors;
• one or more interconnect traces, each interconnect trace interfaced to one of the contact structures and configured to interface the contact structures to an external device when the flexible substrate and the electrode portion are inserted into the external device;
• and
• a further enclosure formed on the same side of the flexible substrate as the one or more connectors and the contact structures, wherein the connectors are at least one of within the further enclosure and on the further enclosure, wherein the enclosure and the further enclosure form an interlock that insulates the further portions of the electrode traces and the contact structures from an ambient environment when the connectors are mated to the further connectors, and wherein the external device is configured to sense data regarding the ambient environment via one or more of the electrodes when the connectors are mated to the further connectors and the flexible substrate and the electrode portion are inserted into the external device.
