The invention provides a kind of electrochemical sensor, such as, when this sensor is by subcutaneous being inserted in the skin of patient, this electrochemical sensor adopts and is exposed with the multiple electrode zones with bioresorbable.The electrode zone exposed is arranged symmetrically with, and makes when AC signal is applied to sensor, produces symmetrical Potential Distributing.Advantageously, the sensor of instructing according to these can be used together with AC signal, to determine the characteristic of sensor, and therefore improve sensor performance.These instructions additionally provide a kind ofly has the biocompatible sensor be exposed with the multiple reference electrode regions with bioresorbable. |
