Abstract
Each micro electrode of a high-density micro electrode array is connected to the same conducting wire. Serial switches enable sequential electrical connection of the micro electrode array. Given reasonable temporal resolution, the separation interval of two consecutive instances of the same micro electrode entering the ON state matches the temporal resolution. The micro electrode array has simple layout and small area, thereby maximizing the number of micro electrodes installed per unit area.
Claims15
A high-density micro electrode array, comprising:
- a plurality of micro electrodes connected to a main conducting wire, wherein an electrical signal is obtained through measurement of every micro electrodes and is transmitted via the main conducting wire;
- a plurality of switch units corresponding in positions to the micro electrodes, wherein every switch unit is connected in between the main conducting wire and each 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;
- and
- a substrate for carrying the micro electrodes, the conducting wire and the switch units so as to form a high-density micro electrode array.
A serial control method of a high-density micro electrode array, comprising the steps of:
- providing a micro electrode array, the micro electrode array comprising a plurality of micro electrodes for generating an electrical signal;
- and
- providing a serial switch array connected to the micro electrode array, wherein a first time interval is defined as a time interval of an ON state of the micro electrodes, allowing a plurality of electrical signals generated by the micro electrodes to be sequentially transmitted via a main conducting wire.
