1. An extraction device for extracting an analyte in living tissue through skin, the device comprising:
- a first path-forming electrode part;
a first extraction electrode part for extracting an analyte;
a through-current electrode part; and
a power supply part for supplying electrical energy to the first path-forming electrode part, the first extraction electrode part, and the through-current electrode part, for forming analyte transmission paths in the skin for the passage of the analyte, and for extracting the analyte at the first extraction electrode part;
wherein the first path-forming electrode part comprises a first path-forming electrode connected to the power supply part, and a first chamber comprising purified water/ion-conductive material, wherein the purified water/ion-conductive material contacts the first path-forming electrode;
wherein the first chamber is configured such that the purified water/ion-conductive material;
is configured to contact the skin over an area of less than 25 mm2; and
wherein, during formation of the analyte transmission paths, the first path-forming electrode part is connected to the power supply part; and
wherein, during analyte extraction, the first path-forming electrode part is disconnected from the power supply part and the first extraction electrode part is connected to the power supply part.
