Abstract:
1. A high-density micro electrode array positioned on a substrate of a sensing portion of a sensor, comprising: a plurality of micro electrodes arranged in series on the substrate of the sensing portion of the sensor and connected to a single main conducting wire on the substrate of the sensing portion of the sensor, wherein electrical signals measured by the micro electrodes respectively, are transmitted via the main conducting wire; and a plurality of switch units positioned on the substrate of the sensing portion of the sensor, arranged in series with the micro electrodes, and each connected in between the main conducting wire and a corresponding one of the micro electrodes in order to control an ON state and an OFF state of transmission paths between the main conducting wire and the micro electrodes, wherein, under control of the switch units, the micro electrodes one by one enter the ON state and after a first time interval therefrom switch to the OFF state, the first time interval being determined by dividing a least temporal resolution of the electrical signals by a quantity of the micro electrodes, wherein the electrical signals leave the same micro electrode one by one at a second time interval.
