Question

Base resistance value of interdigitated electrode structure is

Answer 1

The IDEs (as stated in [7]) consist of 614 electrodes with a thickness of 110 nm, and 5 μm width and interspacing. This geometry is imposed by the resolution limit of the applied in-house lithography process. The length of the electrodes is 3.25 mm, providing a total sensing area of about 20 mm2.

Answer 2

The ideal base resistance value of interdigitated electrode structure is infinity.

• The interdigitated electrode structure is made up of two interdigitated comb-like electrode structures that may be addressed independently.
• The geometry and topologies of the interdigitated electrodes, on the other hand, affect both impedance and capacitance biosensors.
• The optimal base resistance value of an interdigitated electrode configuration is zero.
• Interdigitated capacitors are utilized to improve the structure's effective capacitance and the sensor's effective active area.
